Fused Mullite
Fused Mullite is produced by melting mixed pure quartz sand and industrial alumina in huge electric arc furnaces. With the high content of mullite crystal, high melting point, excellent thermal stability, low reversible thermal expansion and resistance to thermal shock and chemical corrosion at high temperature. It can be widely used as linning bricks in glass body kiln and large hot wind furnace in iron-making blast furnace, as well as in ceramic kiln and petro chemistry.
