Sintered mullite is made, using high purity starting materials of industrial alumina and kaolin, through fine grinding, briquetting and sintering at high temperature in shaft kiln.
The product is featured by high purity, well developed mullite crystal, uniform thermal expansion, good thermal shock resistance, high refractoriness under load, low creep at high temperature and good chemical stability. It is an important synthetic material for refractories used in industries of iron and steel-making, ceramics, construction material, chemical, foundry, etc.
