1. Mullite Sand Introduction
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. It is generally used in stainless steel precision casting process. When the refractory degree is about 1750 degrees, the higher the aluminum content in mulberry sand is, the lower the iron content is. The smaller the dust is, the better the quality of mullite product is.
