Clay is a kind of cohesive soil, which contains little sand, and water is not easy to pass through, so it has good plasticity.

Generally speaking, clay is formed after silicate minerals are weathered on the earth's surface. Generally, it is weathered in situ, with large particles and composition close to the original stone, which is called primary clay or primary clay. This kind of clay is mainly composed of silica and alumina, which is white and fire-resistant, and is the main raw material for preparing porcelain clay.

Clay, also known as clay, has very small particles (

Clay is generally formed after aluminosilicate minerals are weathered on the earth's surface. But some diagenesis can also produce clay. The appearance of clay in these processes can be used as a sign of the progress of diagenesis.

Clay 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.
