Fire Clay Bricks Fire Bricks For Pizza Oven
Kiln Fire Clay Brick is made from clinker clay by mixing, forming, drying, sintering and machine pressing moulding with good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.
The mineral composition of heavy dense fire clay bricks mainly is kaolinite(Al2O3·2SiO2·2H2O) and 6%~7% impurities (oxides of potassium, sodium, calcium, titanium and iron). The firing process of blast furnace refractory tiles is mainly due to the continuous dehydration of kaolinite to form crystallization of mullite (3Al2O3·2SiO2). SiO2 and Al2O3 in the yellow fire clay bricks form a eutectic low-melting silicate with impurities during the firing process, surrounding the mullite crystal.
