Fused Mullite
Description:
Fused mullite was manufactured from pure quartz sand and industrial alumina in super large electric arc furnace.
Features:
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.
Application:
Fused Mullite 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. It is also used in refractory and ceramic industry.
