1. Mullite Sand Introduction
Mullite is a series of aluminum silicate minerals collectively, the minerals scarce. Mullite is an aluminum silicate minerals at high temperatures generated, it will form artificial heating aluminum silicate mullite. Natural mullite crystals and needles are radially elongated clusters. Mullite quarry is used to produce high temperature refractory material.
