What are the three main raw materials of ceramics? What are the three main raw materials of traditional ceramics?

1, plastic raw materials. The mineral components of plastic raw materials are mainly clay minerals, all of which belong to layered silicates, and their particles are generally below micro-particle size, which has certain plasticity. Such as kaolin, porous soil, bentonite, porcelain clay, etc. Plasticity raw materials mainly play the role of plasticization and combination in production, endowing the green body with plasticity and grouting formability, and ensuring the strength and various use properties of the sintered dry body, such as mechanical strength, thermal stability and chemical stability. They are the foundation of clay ceramics forming and porcelain forming.

2. Poor raw materials. The mineral components of poor raw materials are mainly non-plastic oxides of silicon and aluminum and oxygen-containing salts. Such as timely, opal pyrophyllite, clinker after clay calcination, waste porcelain powder, etc. Inferior raw materials play a role in reducing viscosity in production, which can reduce the viscosity of blank. After firing, part of it should be dissolved in feldspar glass in time to improve the viscosity of liquid phase and prevent high temperature deformation. After cooling, it plays a skeleton role in the porcelain blank.

3. Fluxing raw materials. The mineral components of flux raw materials are mainly alkali metals, oxides of alkaline earth metals and oxygen-containing salts. Such as feldspar, limestone, dolomite, talc, lepidolite and granite. They play an auxiliary role in production. After high-temperature melting, the partial decomposition products of timely and kaolin can be dissolved, and the molten high-viscosity glass can play the role of high-temperature cementation. It also reduces viscosity at room temperature.
