Mullite is a refractory material mainly composed of mullite minerals, which has important applications in various fields. The following is a detailed introduction for you:

Casting field

-Molds and cores: Molar sand has the characteristics of high temperature resistance and low thermal expansion coefficient, which can be used to make molds and cores. It can withstand the high temperature impact of molten metal, ensuring the dimensional accuracy and surface quality of castings.

-Coating: As the main raw material for casting coating, it is applied to the surface of the mold to prevent the metal liquid from sticking to the sand and improve the surface smoothness of the casting.

ceramic industry

-Refractory materials: used to manufacture refractory bricks, kiln furniture, etc. for ceramic kilns, maintaining good structural stability in high temperature environments.

-Ceramic blanks: Adding them to ceramic blanks can improve their sintering and mechanical properties.

Other areas

-Refractory products: used in the production of refractory castables, refractory ramming materials, etc., for high-temperature equipment in industries such as metallurgy and building materials.

-Abrasive: Due to its high hardness, it can be used as an abrasive for grinding and polishing material surfaces.
