Alumina Ceramics:
Pottery can be made from ordinary clay and fired. Porcelain needs to choose specific materials to be made from kaolin. The firing temperature can become pottery at the required temperature stage of pottery, such as ancient white pottery. At the temperature required for firing kaolin, the green body is made into porcelain. However, when the body made of clay made of pottery is generally 1200 ° C, it is impossible to become porcelain and it will be fused to glass. Even if the body of the pottery is thin, it is not translucent. For example, the black pottery of Longshan culture is as thin as an eggshell, but it is not transparent. Regardless of its thickness, porcelain carcasses are translucent. There are two types of pottery: unglazed and hanging glaze. The glaze of the pottery can be melted at a lower firing temperature. There are two kinds of glazes for porcelain, which can be fired with the carcass at high temperature once, or can be hung with low-temperature glaze on high-temperature plain fired tires, and fired for the second time at low temperature. Porcelain was also called kiln in ancient times. Porcelain is made of porcelain clay (porcelain stone) as raw material. After being shaped, dried and glazed, it is fired at a high temperature of about 1300oC. The appearance is hard and dense, the surface is smooth and clean, the colloid is thin and translucent, the sound is clear when tapped, and does not absorb water.
1. The raw material of pottery is clay. Clay is preferable everywhere and is not restricted by geographical conditions.
2, pottery firing temperature is generally lower than 800 degrees Celsius.
3. The density of the pottery is small and the water absorption rate is high.
4. Pottery is generally composed of pottery tires only.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
