Ceramics are a general term for ceramics and porcelain, and the existence of ceramics was found as early as about 8000-. The ceramic materials are mostly oxides, nitrides, borides, carbides, and the like. Common ceramic raw materials comprise clay, alumina, kaolin and the like, and the main raw materials of the ceramic are silicate minerals from the nature, so the ceramic belongs to the category of silicate industry with the industrial fields of glass, cement, enamel, refractory materials and the like. The formed ceramic product generally has high hardness but poor plasticity. The ceramic products play an important role in the development of electronic science, in addition to the use of tableware, utensils and decorations. The ceramic is prepared by crushing, mixing, molding and calcining raw materials, wherein the calcining temperature is very important, the ceramic can be prepared into water when the ceramic is burnt to 700 ℃, and the ceramic is vitrified when the ceramic is burnt to 1230 ℃, so that the ceramic can completely absorb no water, resist high temperature and resist corrosion. Therefore, the performance of the ceramic can be designed and improved in a targeted manner, and the ceramic can be applied to a plurality of technical fields to form various novel and interesting creative products or high-tech products.
