Products Description


Mullite sand for manufacturing Cordierite Refractory
Mullite, a silicate alumina refractory, is commonly used in stainless steel precision casting processes.The fireproof degree is
about 1750 degrees. The higher the content of aluminum and iron in mullite sand is, the lower the content of iron is and the
smaller the dust is, the better the product quality is.Morai sand is made from kaolin sintered at high temperature.

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.
