Cordierite-mullite brick is of low thermal
expansion coefficient, excellent stability of thermal shocking, it
is used in assembly brick for hot blast stove.
Sintered mullite brick mineral component is mullite phase. It has
the advantage of high temperature structural strength, strong resistance
to chemical corrosion. It is used in the lining of high temperature
kiln.
Silimanite bricks possesses the better refractoriness temperature
under load and the good stability of thermal shocking. It is mainly
used in the blast furnace, wind pipe of the blast heating cupola,
the lime kiln, the discharging channel and cover board of the glass
melting kiln.
