Kaolin is not a type of clay, the difference between kaolin and high white clay

1. Clay: It is a hydrous aluminosilicate mineral, which is a widely distributed colloidal matte and cohesive soil.

It is malleable when wet and hard when roasted.

Its main components are decomposed igneous and metamorphic rocks, and its basic composition is kaolin and other bauxite minerals.

Clay has unique plasticity and bonding, that is, molding performance and firing performance.

In summary: clay ceramic raw material is a hydrous aluminosilicate mineral, which is formed by feldspar rocks after long-term weathering and geological action. It is a mixture of a variety of fine minerals, the main chemical composition is silica, aluminum oxide and crystalline water, and contains a small amount of alkali metals, alkaline earth metal oxides and coloring oxides.

Clay has unique plasticity and bonding, and it can be kneaded into a mud mass after being swelled with water to shape the desired shape, and become hard and dense after roasting. This performance forms the basis of the process of ceramic production. Clay is the basic raw material for ceramic production, which is widely distributed in nature, with large reserves and a wide variety, and is a valuable natural resource.

2. Kaolin:

Kaolin is mainly composed of kaolinite cluster minerals such as tiny flakes, tubulars, and lamellar minerals less than 2 microns.

Kaolinite cluster minerals: composed of kaolinite, dikailite, perlite, halloysite, etc., the ideal chemical formula is Al2O3-2SiO2-2H2O, its main mineral components are kaolinite and hydrous kaolinite, in addition to kaolinite cluster minerals, there are other minerals such as montmorillonite, illite, pyrophyllite, quartz and feldspar. The chemical composition of kaolin contains a large amount of Al2O3, SiO2 and a small amount of Fe2O3 and TiO2, as well as trace amounts of K2O, Na2O, Cao and MGO.

White pottery is made of kaolin. Now the internationally used kaolin scientific name - kaolin is ** kaolin in the eastern suburbs of Jingdezhen Kaolin Village.

Kaolin's plasticity, cohesiveness, certain drying strength, sintering and whiteness after firing and other special properties make it the main raw material for ceramic production; White, soft, highly dispersed, adsorption and chemical properties and other excellent process properties, so that it has been widely used in the paper industry. In addition, kaolin is widely used in industrial sectors such as rubber, plastics, refractories, petroleum refining, as well as in agriculture and defense cutting-edge technologies. Depending on the use and need, it can be processed, treated, and purified, and they can all be used to make activated clay.

In summary: kaolin ceramic raw material is a clay composed mainly of kaolinite. It was named after Gaoling Village, which was first discovered in the northeast of Jingdezhen, Jiangxi Province.

Its chemical formula is: AL203 2SI02 2H20, and the percentage of weight is96%。

Pure kaolin is dense or loose in the form of blocks, white and light gray in appearance. When polluted by other impurities, it can be black-brown, pink, beige, etc., with a slippery feeling, easy to knead into powder by hand, the color is white after calcination, and the refractory degree is high, which is an excellent raw material for porcelain. Reference.

Kaolin: pure clay, the main component is aluminum and silicon oxide (note: chemical formula Al2O3·3SiO2·6H2O).

White or off-white powder, with a melting point of about 1750 degrees Celsius, is an important raw material for the ceramic industry and other chemical industries. Because the quality of kaolin produced in Jingdezhen, Jiangxi Province, China is the best, so it is called kaolin.

Kaolin, also called porcelain clay, is the raw material for firing porcelain.

There is no difference between kaolin and high white clay, and the two are basically the same substance.

Kaolin, composed of kaolinite group minerals (kaolinite, dikailite, halloysite, etc.), its main mineral components are kaolinite and hydrous kaolinite, usually in the shape of tiny flakes, tubular, laminated and other shapes.

Kaolin is very widely used, mainly due to its special properties such as nuclear plasticity, cohesiveness, certain drying strength, sintering and whiteness after firing, making it the main raw material for ceramic production.

1. Kaolin is a non-metallic mineral, which is a kind of clay and clay rock dominated by kaolinite clay minerals.

2. Kaolin is also known as dolomite because it is white and delicate. It is named after Gaoling Village, Jingdezhen, Jiangxi Province. Its pure kaolin is white and delicate, soft soil, and has good physical and chemical properties such as plasticity and fire resistance.

Its mineral composition is mainly composed of kaolinite, halloysite, mica, illite, montmorillonite, quartz, feldspar and other minerals.

Answer: Kaolin is partially cleavage.

Explanation: Kaolin is a clay-like substance obtained from kaolinite. Kaolinite is a mineral belonging to the silicate minerals, and its crystal form is hexagonal.

In terms of crystal structure, there are three SiO4 tetrahedra and one ALO6 octahedron in the unit cells of kaolinite. In the preparation of kaolin, kaolinite is ground into extremely fine particles, and then water or other chemical reagents are added, and after a series of treatment processes, kaolin is finally formed.

During the preparation of kaolin, the crystal structure of kaolinite will undergo certain cleavage, but not complete cleavage. That is, there are still a certain number of kaolinite crystals in kaolin, and these crystals may have an impact on the properties of kaolin.

Expansion: Kaolin is an important industrial raw material, widely used in ceramics, electronics, building materials, cosmetics and other fields. In the preparation process of kaolin, how to control the cleavage degree of kaolinite and how to improve the purity and quality of kaolin have always been the focus of research in related fields.

Complete cleavage. It has extremely complete cleavage, hardness, and relative density. Kaolinite clay is also known as "kaolin", commonly known as "porcelain clay".

It is composed of kaolinite with a content of more than 90%. It was found in the "Gaoling" place near Jingdezhen, Jiangxi Province, China. Generally, kaolin raw ore rotten contains a small amount of montmorillonite, illite, diaspore, quartz, mica, pyrite, calcite, organic matter and other impurities.

Kaolin is a white powder that belongs to clay minerals and is widely used in the pottery industry due to its ability to become very hard during the sintering process. The origin of kaolin mainly comes from the sediment in the mine, which is obtained after mining, grinding and other processes. Before grinding, there may be some particles in the kaolin, lumps and solid surface appendages.

As a result, the cleavage degree and quality of kaolin are affected. For industrial kaolin, the degree of cleavage usually needs to reach a certain level to ensure the performance and quality of transportation.
