What is the best raw material for ceramics? What are the ceramic materials

Ceramics is a general term for pottery and porcelain. The Chinese invented pottery as early as about 8000 2000 BC (Neolithic Age). The components of ceramic materials are mainly silicon oxide, alumina, potassium oxide, sodium oxide, calcium oxide, magnesium oxide, iron oxide, titanium oxide, etc.

Common ceramic raw materials are clay, quartz, potassium albite, etc. Ceramic raw materials generally have high hardness, but poor plasticity. In addition to the use of food utensils and decorations, it also plays an important role in the development of science and technology.

Ceramic raw materials are processed from clay, quartz, and feldspar, which are a large number of the earth's original resources. The nature of clay is tough, it can be molded when exposed to water at room temperature, can be carved by micro drying, can be pressed semi-dry, and can be ground with full dryness; Fired to 900 degrees can be made into pottery, which can be filled with water; When burned to 1230 degrees, it is porcelainized, which can completely non-absorbent water and is resistant to high temperature and corrosion. The flexibility of its usage, strict control of ceramic manufacturing, must control the quality of raw materials and manufacturing process in the manufacturing process, in order to produce high-quality ceramics; Of course, the procurement of raw materials can be queried on the industry's top query (Zhongtaolian platform), I hope it will help you!

The materials of ceramics are silicate, aluminosilicate, kaolin, metal nitride, boride, etc. Silicate: refers to the compound formed by the combination of silicon, oxygen and other chemical elements (mainly aluminum, iron, calcium, magnesium, potassium, sodium, etc.).

Aluminosilicate: Aluminosilicate is a class of inorganic substances, which are colorless crystals, and the ratio of alumina and silicon oxide is not constant. Kaolin:

It is a non-metallic mineral, mainly clay and clay rock of kaolinite clay minerals. Because it is white and delicate, it is also called dolomites. <

The materials of ceramics are silicate, aluminosilicate, kaolin, metal nitride, boride, etc.

1. Silicate: refers to the general term of compounds formed by the combination of silicon, oxygen and other chemical elements (mainly aluminum, iron, calcium, magnesium, potassium, sodium, etc.). It is widely distributed in the earth's crust and is the main component of most rocks and soils.

2. Aluminosilicate: Aluminosilicate is a class of inorganic substances, which are colorless crystals, and the ratio of alumina and silicon oxide is not constant.

3. Kaolin: It is a non-metallic mineral, mainly clay and clay rock of kaolinite clay minerals. Because it is white and delicate, it is also called dolomites.

4. Metal nitride: Nitride is a binary compound formed by nitrogen and an element with less electronegativity than it. Nitrides formed by the direct combination of transition elements and nitrogen are also known as metallic nitrides.

They belong to the category of "interfilled compounds," so named because nitrogen atoms occupy interstitial positions in the metal lattice.

5. Boride: Boride is a binary compound formed by boron, metal, and some non-metals (such as carbon). It can be expressed by the general MMBN, which is generally an interfilling compound and does not follow the valency rule. They are all crystals with high hardness and melting point, and are chemically stable.

1. Ceramics are made of inorganic non-metallic materials, which are mainly materials composed of oxides, carbides, nitrides, halogen compounds, borides, silicates, aluminates, phosphates, borates and other substances of certain elements.

2. The original ceramics refer to the general term of pottery and porcelain. That is, the formed sintered body obtained by high-temperature sintering. Traditional ceramic materials mainly refer to aluminosilicate.

3. At the beginning, people did not have high requirements for the selection of aluminosilicate, the purity was not large, the particle size of the particles was not uniform, and the molding pressure was not high. At this time, the obtained ceramics are called traditional ceramics. Later, it developed to high purity, small and uniform particle size, high molding pressure, and the sintered body obtained by sintering is called fine ceramics.

Ceramic materials refer to a class of inorganic non-metallic materials made of natural or synthetic compounds through forming and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance, oxidation resistance and so on. It can be used as a structural material, a tool material, and because ceramics also have some special properties, it can also be used as a functional material.

Hello dear I am glad to serve you: the three major raw materials of ceramics The raw materials of ceramics mainly include: plastic raw materials, barren raw materials, and flux raw materials.

1. Plastic raw materialsThe mineral components of plastic raw materials are mainly clay minerals, which are all silicates with layered structure, and their particles generally belong to minerals with a microscopic particle size below (less than 10 m) and have a certain plasticity. Such as kaolin, hydro ridge clay, bentonite, porcelain clay, etc. Plasticizable raw materials mainly play a role in plasticization and combination in the production, which gives the blank plasticity and the forming performance of Lu group grouting to ensure the strength of the dry billet and various performance after firing, such as mechanical strength, thermal stability, chemical stability, etc., they are the basis for molding, and also the basis for porcelain formation of clay ceramics.

2. The mineral components of barren raw materials are mainly non-plastic silicon, aluminum oxidation amateurs and oxygenated salts. Such as quartz, opal pyrophyllite, clinker after clay calcination, waste porcelain powder, etc. Barren raw materials play a viscosity reduction role in production, can reduce the viscosity of the blank, after firing, part of the quartz is dissolved in the feldspar glass, improve the viscosity of the liquid phase to prevent high temperature deformation, and play a skeleton role in the porcelain blank after cooling.

3. The mineral components of flux raw materials are mainly alkali metals, oxides and oxygenated salts of alkaline earth metals. Such as feldspar, limestone, dolomite, talc, lepidolite, granite, etc. They play a role in the production of panicle cracking and melting, after high temperature melting, a part of the quartz and high-pitch soil decomposition products can be dissolved, and the melted high-viscosity glass can play a role in high-temperature cementation.

There are many kinds of ceramic things in our market, such as ceramic sanitary ware, its wear resistance is good, the product is environmentally friendly, we have pollution when using, and its materials are rich, and it is not expensive, but the materials of ceramics are also a lot, the selection of good ceramics, of course, its materials are also critical, so let's follow together to understandRaw materials for ceramicsWhat are the characteristics of ceramic raw materials, I hope it can help you.

1. What are the raw materials of ceramics?

1. Oxide raw materials.

2. Alumina is one of the most widely used raw materials in new ceramic products, with a series of excellent properties. In addition, it is also an important raw material for high-temperature refractory materials, abrasives, abrasives, laser materials and alumina gemstones.

3. Zirconia is an important raw material for high-temperature structural ceramics, electronic ceramics and refractories.

1. Mechanical properties: Ceramic materials are the materials with the best stiffness and the highest hardness among engineering materials, and their hardness is mostly above 1500HV. The compressive strength of ceramics is higher than that of this sock group, but the tensile strength is low, and the plasticity and toughness are poor.

2. Thermal characteristics: Ceramic materials generally have a high melting point (mostly above 2000), and have excellent chemical stability at high temperatures; The thermal conductivity of ceramics is lower than that of metal materials, and ceramics are also good thermal insulation. At the same time, the linear expansion coefficient of ceramics is lower than that of metals, and ceramics have good dimensional stability when the temperature changes.

3. Electrical characteristicsMost ceramics have good electrical insulation, so they are used to make various voltages, and can be used to make capacitors, ferroelectric ceramics can change their shape under the action of an external electric field, convert electrical energy into mechanical energy, and can be used as amplifiers, record players, ultrasonics, sonars, medical acoustic spectrometers, etc. A few ceramics also have the characteristics of semiconductors and can be used as rectifiers.

4. Chemical characteristics: Ceramic materials are not easy to oxidize at high temperatures, and have good corrosion resistance to acids, alkalis and salts. Optical propertiesCeramic materials also have unique optical properties, which can be used as solid-state laser materials, optical fiber materials, optical orange storage, etc., and transparent ceramics can be used for high-pressure sodium lamps, etc.

5. Magnetic ceramics (ferrites such as: MGFE2O4, CuFe2O4, Fe3O4) have a wide range of prospects in the application of audio tapes, records, transformer cores, and large computer memory components.

The above is for you to introduce what are the ceramic raw materials and what are the characteristics of ceramic raw materials, ceramic materials refer to a class of inorganic non-metallic materials made of natural or synthetic compounds through forming and high-temperature sintering, because ceramics also have some special properties, and can be used as functional materials.

Ceramics, we often see, sinks, bathtubs, etc. are more ceramic products, but you knowRaw materials for ceramicsWhat are they? Daily ceramic raw materials are divided into three categories: clay raw materials with plasticity, quartz raw materials with non-plasticity (barren raw materials) and flux raw materials.

Let's take a closer look!

Raw materials for ceramics

Clay raw materials are one of the main raw materials for daily ceramic raw materials. The amount of clay raw materials in fine porcelain ingredients often reaches 40=60%, and the amount can be increased in pottery and stoneware. The reason why clay is the main raw material for ceramic products is due to its plasticity and sintering properties.

The main minerals in the clay used in ceramics are Gaotongliang group ridge stones, montmorillonite and illite (mica), etc., in addition to rare diaspore.

Quartz raw materials (barren raw materials): There are several quartz raw materials and materials commonly used in the ceramic industry: vein quartz, sandstone, quartzite, quartz sand.

The role of quartz in the production of ceramics is to be added to the ceramic blank as a barren raw material, and it is one of the main components in the ceramic body, (commonly known as aggregate). It has an important influence on the forming and firing of green bodies in the production of ceramics.

Flux raw materials: the most important mineral raw materials containing alkali metal oxides, in addition, some minerals containing alkaline earth metals can also be used as flux raw materials, among which carbonate slag messes containing calcium oxide and magnesium oxide are more common. Feldspar is the most commonly used flux raw material in ceramic raw materials, and is used as a basic ingredient such as blank, glaze, pigment flux in ceramic production, with a large amount and one of the three major raw materials for ceramics.
