Sintered mullite 

Natural sintered mullite is manufactured directly from natural high-quality bauxite, calcined in kiln at temperature over 1750 degrees.It is characterized by high bulk density, stable quality , stability thermal shock resistance, low index of high temperature creep and chemical corrosion resistance performance,it is the perfect raw material for variety of shaped and monolithic refractory, advanced sanitary ware embryonic body, precision casting models and so on.

White Fused Mullite 

White Fused Mullite, is a first quality refractory material, composed of massive crystals of mullite which are formed during cooling after fusion. It confers high melting point, excellent thermal stability, low reversible thermal expansion, low porosity, high resistance to thermal shock and chemical corrosion at high temperatures.
