1. Plastic raw materials. This raw material is mainly composed of clay minerals, this silicate has a layered structure, small particles, and has certain plasticity. When making ceramics, it will have the function of bonding and plasticizing, so that the grouting can be formed quickly, so that the blank can also be easily shaped, and at the same time has stronger chemical and thermal stability.
2. Barren raw materials. There are three main components, including oxygen-containing salts, aluminum oxides, silicon oxides, etc., and these mineral components are not plastic. When making ceramics, it will play the function of reducing viscosity, so that the viscosity of the blank is reduced. Some quartz is fused with feldspar glass to avoid high-temperature deformation.
3. Flux raw materials. Mineral components such as alkali metals, oxygen-containing salts and oxides of alkaline earth metals are the main functions, and the main function is to assist the melting, and in the state of high temperature melting, some kaolin and quartz can be dissolved, so as to achieve the purpose of high temperature cementation. The more common materials are granite, dolomite and feldspar.
4. Functional raw materials. It is also a raw material used to make ceramics, and although it does not play a major role, it is also indispensable. In the process of making ceramics, adding an appropriate amount of such raw materials can improve some performance, improve the process, and enhance the overall appearance and value.
