High Temperature Sintering Refractory Sand With Low Thermal Expansion Coefficient

Precision Casting Sand of Refractory Sand with Low Thermal Expansion and High Alumina

1. Production Introduction 

Precision Casting Sand of Refractory sand 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
