Problems solved by technology

[0002] For the kiln furniture used to support fired products in the kiln, it is required to have better thermal shock resistance and low energy consumption. Cordierite-mullite materials are used as high-grade materials because of their low expansion coefficient and strong high temperature resistance. Kiln furniture materials, but due to the high cost of cordierite and mullite materials and the low firing rate of synthetic materials, the production cost of cordierite-mullite kiln furniture is high, and the development is limited; The body density of some cordierite-mullite kiln furniture materials is 1.75-2.15g / cm3, the weight of the product is large, and the heat absorption is large, which has a great impact on the production of raw materials and the fuel consumed in the kiln.
[0003] Waste ceramics are waste materials produced in the production process of ceramics or ceramics that have lost their use value. The usual treatment methods are downgrading and landfilling, resulting in waste of materials and certain adverse effects on the environment. Further improvement is needed.
