Stable physicochemical Chamotte Sand and Powder for Precision Investment Casting Industry with Low Dust and Iron Content

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
