High Temperature Sintering Casting Sand , Mullite Sand With Strong Fire Resistance

Mullite Sand of Flint Clay Used for Casting Sand Especially Precision Casting with Low Thermal Expansion

1. Description:

Mullite is made of kaolin by high temperature sintering.

The chemical components of mullite are all chemical substances with strong fire resistance, and their properties are relatively stable.

It mainly includes: alumina, silica, etc., the content of alumina is between 42% and 46%, and the content of silica is between 51-53%. In addition, there are less substances: iron oxide, sodium superoxide, potassium superoxide, titanium oxide, magnesium oxide, etc

2. Application:

Refractory sand is widely used in investment casting, gypsum filling V method and vacuum suction casting, as well as large, medium and small steel casting, copper casting, furnace lining refractories, as well as water glass, refractory products, concrete materials, etc. Widely used in machinery, aviation, weapons, metallurgy, petroleum, heat preservation, sintering, construction and other industries
