Mullite sand is one kind of natural mullite, it is made from pure material and through high temperature at 1300℃ calcined, and suitable for precision casting. our products have been processed by special technique and equipments, featured with stable casting and sheeling property. It has ben applied by precison casting factories in Japan, Europe and etc. for long time.

Characteristics:

Low thermal expansion coefficient, high thermal shock resistance

High chemical stability and corrosion resistance

Suitable particle shape and uniform size distribution for shell casting

Low iron and dust content

High hardness, abrasion resistance to prevent generation dust storage and operation
