Alumina Ceramics:
When it comes to ceramic materials, it is inevitable to talk about pottery and porcelain separately. Ceramics that we often talk about refer to the two types of pottery and porcelain. In the field of creation, pottery and porcelain are both indispensable and important parts of ceramic art, but pottery and porcelain are qualitatively different.
Ceramic materials: Compared with porcelain, the texture of ceramics is relatively loose, and the particles are relatively coarse. The firing temperature is generally between 900 ° C and 1500 ° C. The temperature is lower. The color and luster after firing are naturally interesting, simple and generous, and have become many artists. One of the favorite modeling performance materials. There are many types of pottery, such as black pottery, white pottery, red pottery, gray pottery, and yellow pottery. Red pottery, gray pottery, and black pottery use pottery with higher iron content as raw materials. Iron pottery clay is red under oxidizing atmosphere , It is gray or black under reducing atmosphere.
Porcelain material: Compared with pottery, the texture of porcelain is hard, fine, forbidden, high temperature resistance, rich in glaze, etc. The firing temperature is generally around 1300 ° C. Some people often describe porcelain as "sound like a magpie, bright as a mirror, Yan Ruyu, "Thin as thin as paper", porcelain mostly feels noble and gorgeous, which is the opposite of the simplicity of pottery. Therefore, when many artists create ceramic art, they will emphasize the distinct sensory enjoyment brought by the texture of pottery or porcelain. Therefore, it is necessary to analyze and compare the characteristics of two different materials before creating.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
