What can you do with clay?

1. Manufacturing sintered bricks and tiles; Making pottery, porcelain, tiles, tiles, etc. ; Mixing with limestone and calcining to obtain cement; Modeling in industry, model making and art, artists use clay as a model, but it is also suitable for directly molding works of art with clay.

2. Used as an ion exchanger in drinking water treatment and other chemical processes; Kaolinite is the raw material of porcelain, which can also make the surface of paper particularly smooth and absorb ink, and can even be used in advanced daily necessities such as facial cleanser. Ceramsite is used as isolation layer in construction industry and soilless culture.

3. Sealed landfill; Used as filler in pigment industry and pharmaceutical industry; Used in catalytic converters. Can be used to make dolls, embossed wall decorations, artificial flowers, dolls, fruits, etc. In addition, the clay is clean, light and non-sticky, and the finished clay works can be preserved for 4-5 years.

Clay is generally formed by weathering silicate minerals on the earth's surface. It is an important mineral raw material. It consists of various hydrated silicates and a certain amount of alumina, alkali metal oxides and alkaline earth metal oxides, and contains impurities such as feldspar, mica, sulfate, sulfide and carbonate.

The particles of clay minerals are fine, often in the range of colloid size, crystalline or amorphous, most of them are flaky, and a few are tubular and rod-shaped.

Clay minerals are plastic when wetted by water, can be deformed under small pressure and can remain unchanged for a long time, and have large specific surface area and negatively charged particles, so they have good physical adsorption and surface chemical activity, and have the ability to exchange with other cations.
