Fireclay Special Shape Al2O3 2H2O Clay Bricks For hot blast stove

Physical and chemical indexes:

Chemical composition (%)

Fireclay Special Shape Al2O3 2H2O Clay Bricks For hot blast stove is made of local top grade fireclay materials under the high temperature according to the lasted national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity. Fire clay refractory brick has wide usage and the largest production. The mineral composition of Fireclay Special Shape Brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6%~7% impurities (oxides of Potassium, Sodium, calcium, Titanium and Ferrum ).

The firing process of Fireclay Special Shape Al2O3 2H2O Clay Bricks For hot blast stove is mainly the process of continuous dehydration and decomposition of kaolin to form mullite (3Al2O3·2SiO2) crystals.

The SiO2 and Al2O3 in the Fireclay Special Shape Al2O3 2H2O Clay Bricks For hot blast stove form eutectic low-melting silicate with impurities during the firing process, which surrounds the mullite crystals.
