Fused Mullite

Details

Manufactured from pure quartz sand and industrial alumina in super-large electric arc furnace,fused mullite has a high content of mullite crystals which confer high melting point,excellent thermal stability,low reversible thermal expansion and resistance to thermal shock and chemical corrosion at high temperature.It is widely used as lining bricks in glass body kiln and large hot wind furnace in iron-making blast furnace,as well as in ceramic kiln and petro-chemistry.
