Product Description

Product Description

Refractory bricks are mainly made from chamotte, flint clay  and combining clay powder, being high pressure pressed and sintered in high temperature.
 
Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.
