Inorganic Non Metallic Materials Engineering 1

Answer]: Inorganic non-metallic materials include inorganic compounds and non-metallic elemental materials formed by various metals and non-metallic elements, with a wide variety of varieties and different uses, and a long history. It is usually divided into two categories: traditional inorganic non-metallic materials and new beam hail inorganic non-metallic materials.

Traditional inorganic non-metallic materials mainly refer to cement, glass, ceramics, bricks, enamels, refractories and other products with natural silicate as the main raw material, most of which are sintered. With the development of modern science and technology, the development of new Li Kai inorganic non-metallic materials such as advanced structural ceramics, functional ceramics, optical fibers, laser materials, intraocular lenses, piezoelectric materials, magnetic materials, bioceramics, new energy materials, and ecological environment materials is changing with each passing day. The development of inorganic non-metallic materials in the 21st century has the characteristics of low-dimensional (on the macro and micro rubber scrambler sails), composite (functional and compositional compounding of materials), intelligence and environmental friendliness, and the main application fields of inorganic non-metallic materials in the 21st century are information, energy, transportation, biomedicine, ecological environment and national defense.

Many of the materials and supplies in our lives are processed by a certain technology, and their prototypes are also different. The more common materials are metallic substances, non-metallic substances, organometallic substances and inorganic technical materials, etc., which have brought great convenience to our life and work through certain technologies, among which inorganic non-metallic materials are a material that plays relatively quickly, and it also has a very good market competitiveness in the market, and the types are also in an increasing state.

(1) The basic properties of new inorganic non-metallic materials

A large class of new inorganic non-metallic materials has relatively strong performance, so it can be seen in different product forms on the market. Its boiling point is particularly cautious, in most cases it belongs to the boiling point of the mixture, and it is insoluble in water, and there is no fixed density value and fixed shape, in addition to its ability to resist corrosion, oxidation and friction is also very strong, which also determines the diversity of this material processing to a large extent, and the development potential of this new material has also increased in the five stars.

(2) The field of application of new inorganic non-metallic materials

1. Industrial field: This new type of inorganic non-metallic materials was originally only the production of some more commonly used building basic materials, such as cement sedan chairs, etc., but with the continuous progress of technology and the continuous increase of new materials, there are many materials with very good adaptability and special effects in the wide oak field of industry, such as advanced ceramics, inorganic coatings, inorganic fibers and other materials.

2 Modern national defense field: Because this new type of inorganic non-metallic material has an unusual crystal structure, and it has no fixed electrons, its chemical properties are relatively special. At the same time, its thermal conductivity, thermal insulation, and light transmittance all make it play an important role in the field of national defense to a large extent, such as the manufacture of high-quality products and the invention of monitoring equipment.

3 Biomedicine field: It is precisely because this material has a very good stability, so it is processed into a large number of medical instruments, utensils and some experimental tools, etc., sometimes it can also help patients to carry out the best training, with the continuous progress of technology, now its status in this field is also in a rising state.

Compared with traditional non-metallic materials, new non-metallic materials have very good performance and great progress, and at the same time have a very good competitiveness compared with other products, which is an important reason for the rapid development of new inorganic non-metallic materials, and it is also an important driving force for its continued development.

The definition of inorganic metal material is as follows:

Inorganic metal materials are all materials except metal materials and high-resolution silver slide materials. Ceramic materials are typical representatives of inorganic metal materials.

Inorganic metal materials have multiple meanings in a broad and narrow sense. In a narrow sense, it is generally only the collective name of pottery and porcelain, which refers to the products made of plasticity clay as the main raw material, adding barren quartz and flux feldspar, and firing after molding, according to the nature of the buried products and the raw materials used and the different firing systems, which can be divided into earthware, pottery, stoneware, porcelain, etc., and are divided into categories such as daily use, construction, health, electrician bending and beating, art ceramics and so on according to different uses.

Inorganic metal materials refer to materials composed of metal atoms and some non-metal atoms, which usually have excellent electrical and thermal conductivity and high strength and hardness. The atomic structure of this type of material has a lattice structure, and due to the high degree of force between the individual metal atoms, inorganic metal materials are usually solid at room temperature. Common inorganic metal materials include iron, copper, zinc, magnesium, aluminum, etc., which are widely used in engineering materials, electronic materials, manufacturing, aerospace and other fields.

In practical applications, inorganic metal materials are often modified by alloys or other metal materials to meet the needs of specific industrial fields.

Inorganic macro metal materials refer to materials composed of one or more metal elements and non-gold ruler elements, which usually have the characteristics of high strength, high hardness, high melting point, high corrosion resistance, good electrical and thermal conductivity. Inorganic metal materials are widely used in industrial, construction, aerospace, electronics, medical and chemical fields. Common inorganic metal materials include iron, copper, aluminum, zinc, titanium, nickel, chromium, etc., which can be used alone or alloyed with other elements to improve their properties.

The research and application of inorganic metal materials is of great significance, which can not only promote the development of materials science, but also contribute to the progress of human society.

Inorganic materials refer to metal materials that do not contain organic elements, and their main components are metal elements and some inorganic impurities (such as oxygen, coins, carbon, nitrogen, sulfur, etc.). Inorganic dust metal materials are widely used in electronics, optics, magnetism, structure and other fields. They have very good physical and chemical properties, including excellent electrical conductivity, excellent processing properties, high strength and hardness, high corrosion resistance, etc.

Commonly used inorganic metal materials include aluminum, copper, magnesium, zinc, titanium, zirconium, iron, nickel, etc. Inorganic metal materials can also be divided into various types according to the preparation method, such as chemical synthesis method, physical synthesis method and mechanical method.

Inorganic non-metallic materials (1).

Speaker: Wang Xianglin, Excellent Chemistry Teacher of Huanggang Middle School 1. Traditional Silicate Materials 1. Introduction to Traditional Silicate Materials (1) Meaning: In the material family, there is a very important class of materials called inorganic non-metallic materials.

Originally, inorganic non-metallic materials mainly referred to silicate materials, so silicate materials are also called traditional inorganic non-metallic materials. Materials such as ceramics, glass, cement and their products can be found everywhere in our daily lives. Because the chemical composition of these materials is mostly silicate, they are generally called silicate materials.

2) Raw materials: Traditional silicate materials are generally produced from clay (the main component), quartz (the main component is SiO2), potassium feldspar (the main component) and albite (the main component) as raw materials. 3) Structural and property characteristics:

These raw materials generally contain silicon-oxygen tetrahedra – the building blocks. Due to the particularity of the silicon-oxygen tetrahedral structure, it is determined that most of the suspended salt materials have the characteristics of strong stability, high hardness, high melting point, insoluble in water, insulation, and corrosion resistance. 2. Ceramics (1) Raw materials:

Clay (2) Equipment: Kiln (3) Process: Mixing Molding Drying Sintering Cooling Ceramics (4) Principle:

At high temperatures, complex physicochemical changes. 5) Types: earthenware, porcelain, stoneware, etc.

6) Color glaze: Before firing, some glaze containing metal and its compounds is coated on the surface of the embryo body of ceramic products, and different redox reactions occur due to the change of air content in the kiln during the sintering process, that is, a layer of color glaze with smooth surface, non-permeable and rich color is produced. Metallic elements in the glaze The amount of air used during firing and the color of the glaze

Excess air Insufficient air

Yellow, red, brown, black, blue, green

Yellow-green, red-purple, brown-brown, black-brown

Preparation of ordinary inorganic non-metallic composite materials.

The characteristics are: high compressive strength, high hardness, high temperature resistance, and corrosion resistance. In addition, cement has excellent characteristics in cementitious properties, glass in optical properties, ceramics in corrosion resistance and dielectric properties, and refractory materials in heat protection and heat insulation, which are unmatched by metal materials and polymer materials.

However, compared with metal materials, it has low breaking strength and lacks ductility, which is a brittle material. Compared with polymer materials, the density is higher and the manufacturing process is more complex.

Special inorganic non-metallic materials are characterized by: Each has its own characteristics. For example:

high-temperature oxidation properties of high-temperature oxides, etc.; high-frequency insulation characteristics of alumina and beryllium oxide ceramics; magnetic properties of ferrite; the light transmission properties of optical fibers; superhard properties of diamond and cubic boron nitride; the conductive properties of the conductor material; The fast-setting and fast-hardening properties of fast-hardening and early-hardening cement. Various physical effects and microscopic phenomena. For example:

Functional conversion characteristics of photosensitive materials between physical and chemical parameters, such as photoelectric materials, thermoelectric materials, piezoelectric materials, gas-electricity of gas-sensitive materials, and humidity-electricity of moisture-sensitive materials. Materials with different properties are compounded to form composite materials. For example:

Cermets, high-temperature inorganic coatings, and materials reinforced with inorganic fibers, whiskers, etc.
