China Sintered mullite Manufacturer and Supplier

Sintered mullite

Short Description:

Sintered mullite is made by using high purity starting materials including industrial alumina and kaolin through ultrafine grinding, briquetting and sintering in high temperature shaft kiln. The product is characterized by high purity, good thermal shock resistance and chemical stability. It is an ideal material for refractories used for metallurgy, ceramics, glass, chemical and other industries. Varieties of JMS-75, JMS-70 and JMS-60 are available with different alumina content.

Size availability:

Aggregates and powders from 15mm to under 45μm can be provided.

Packaging:

25kg/bag, 1000kg/bag or other specific packaging as per users’ requirements are available.
