Sintered mullite using high-quality natural bauxite as raw materials, is proceeded with multi-channel selection process and multistage homogenization, sintered with more than 1750℃ high
temperature. Mullite has the characteristics of high content, high volume density, good thermal shock stability, low creep value at high temperature and good resistance to chemical
corrosion. Because of its good quality and stability performance, Mullite is the production of a variety of stereotypes and non qualitative refractories, advanced sanitary ware billet, crucible, sager,
precision casting and other products ideal raw materials.
Performance of Sintered mullite:
1. High melting point: The melting point can reach 1850°C, which is suitable for extremely high temperature environments.
2. Slag resistance: It has strong resistance to acidic and neutral slags, and is particularly suitable for high temperature acidic environments in the glass and ceramic industries.
3. Excellent thermal shock stability: Due to the low expansion characteristics of mullite, it exhibits excellent thermal shock stability in a rapid temperature change environment, reducing the risk of cracks and spalling.
4. Low expansion rate: The thermal expansion coefficient is low, the thermal stability is excellent, and it is suitable for working conditions with harsh thermal shock conditions.
5. Good density: The sintering process forms a dense microstructure, reduces the porosity, and enhances the material’s resistance to permeability.
