Product Details

Manufacturing Industrial Grade Mullite Sand of Refractory Sands for Casting and Refractory Products Materials

 

1. Production Introduction 

Mullite sand of refractory sand is a kind of high quality refractory raw material, this kind of mineral is rare.

 

Mullite is a mineral produced by aluminosilicate at high temperature.The natural mullite crystals are slender needles and radiated clumps.

 

Mullite is used to produce high temperature refractory.

 

Mullite is a stable binary solid solution under atmospheric pressure in Al2O3-SiO2 system.

We have different grades of refractory sand for you to choose.
