Abstract

The invention discloses a ceramic processing technology which comprises the following steps: 1, modifying bentonite: adding bentonite into a surfactant, stirring at a low speed of 50-100r/min for 10-20min, washing with water, drying, and grinding to 50-100 meshes; in ceramic processing, spodumene is used as a base material, bentonite is treated in a surface agent, then blasting treatment is carried out, wollastonite in the surface agent is inserted into the bentonite in a penetrating mode, meanwhile, the effect of wollastonite on bentonite can be improved through shell powder, and therefore in the hot-pressing calcination process, the spodumene is jointly improved through bentonite and wollastonite.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a ceramic processing technology. Background technique [0002] Ceramics is the general term for pottery and porcelain. Common ceramic materials are clay, alumina, kaolin and so on. Ceramic materials generally have higher hardness, but poor plasticity. In addition to being used in tableware and decoration, ceramics also play an important role in the development of science and technology. The raw material of ceramics is obtained by quenching the earth's original large resource clay. The nature of clay is tough, it can be molded when it meets water at room temperature, it can be carved when it is slightly dry, and it can be ground when it is completely dry; it can be made into pottery when it is fired to 700 degrees, and it can be filled with water; corrosion. The flexibility of its usage has various creative applications in today's culture and technology. Pottery was invente...
