16-30 Mesh Mullite Refractory Sand for Mold Making of Precision Casting and Refractory Products
1. Production Introduction
Mullite 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
