Sintered mullite - Aluminum
Our company's sintered mullite has the characteristics of low impurities, high mullite phase, low thermal expansion rate, good thermal shock stability, high temperature and low creep value.
Sintered mullite - Aluminum is made of high purity raw materials such as industrial alumina and kaolin by ultra-fine grinding, forming and sintering at high temperature by shaft kiln. The product has the characteristics of high purity, good crystal development, uniform expansion, good thermal shock stability, high softening point under load, low creep at high temperature, good chemical stability, etc. It is the ideal raw material for refractory materials in iron and steel metallurgy, ceramics, building materials, chemical industry, casting and other industries. According to the alumina content mullite is classified into SAS-75, SAS-70, SAS-60.
