These products are made from high-purity mullite chamotte. According to different grade, the bricks are put in different percent of Al2O3. Direct burning would make the bricks different synthetic mullite phase.
The temperature ranges from 1200℃ to 1550 ℃.
·High temperature resistance(can directly contact fire)
·Good abrasion resistance
·Low thermal conductivity, low heat storage.
·High hot compressive strength
·Good thermal shock resistance
Ideal refractory lining of furnace for petrochemical, iron and steel industry, for instance, crack furnace, reactor chamber, process heaters, transfer ladle lids, reheating furnace.
·Suitable for all kinds of ceramics and glass kilns.
