Sintered
Mullite |
The
products are made from high quality raw materials, sintered at high
temperature in the Tunnel Kiln or Rotary Kiln. It's highly consistent
in quality, widely used in the production of refractory products
with high thermal shock resistance, low creep property and high
refractoriness.

Fused
Mullite |
Manufactured
from pure quartz sand and industrial alumina in electric arc furnace,
with high melting point, excellent thermal stability, low reversible
thermal expansion and resistance to thermal shock and chemical corrosion
at high temperature, Fused Mullite is widely used as lining brick
in glass body kiln and large hot wind furnace in iron-making blast
furnace, as well as in ceramic kiln furniture and petrochemistry.
