Small Thermal Expansion Coefficient Chamotte Sand and Powder for Casting and Refractory Industry

1. Production Introduction and Application

chamotte sand and powder is made of kaolin or bauxite 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

Chamotte 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
