Our silica insulating fire bricks are some of the best on the market, demonstrated by density up to 0.6 g/cm3. High performance under load, acid-resistant and low slag erosion, excellent high temperature mechanical strength and low thermal conductivity.
Our anorthite thermal bricks are made by blending clay and plaster, when fired, the lime from the plaster reacts with the clay to form anorthite, the plaster decomposes, losing about 70% of its weight, leaving micro porosity and very low thermal conductivity of finished brick.
Our heavy duty thermal bricks are manufactured using a high purity grade material with good performance under load. They are high in tridymite content, display high density, low thermal expansion and low creep rate.
Our fire bricks are manufactured from high purity bubble alumina. The finished product possesses a large volume of closed pores. They are light weight with high temperature resistance, low thermal conductivity, high strength, small re-heating linear change and good thermal shock resistance.
Our silicon carbide fire bricks demonstrate high thermal conductivity, high thermal shock resistance, low thermal expansion coefficient, high corrosion resistance, high bending strength and excellent resistance to liquid aluminium erosion capability.
Our chrome fire bricks are made from chromium oxide, alumina micro powder and other additives according to the target application. They are sintered by a high temperature shuttle kiln. These bricks are highly corrosion-resistant which is important for acid or alkali melts.
Our corundum fire bricks are made using high purity tabular alumina and fused alumina. These thermal bricks demonstrate excellent performance in density, purity, porosity and thermal shock resistance. Our bricks are designed to withstand corrosion attacks and high temperature hydrogen attacks.
Our mullite fire bricks are bonded refractory bricks mainly containing a crystal structure of mullite phase glass phase and a corundum phase achieved through high temperature sintering. These thermal bricks deliver high refractoriness under load, good thermal shock resistance, good erosion resistance and low creep rate.
Our sillimanite fire bricks deliver excellent performance in areas such as refractoriness under load, thermal shock resistance, erosion resistance and a very low creep rate. Mainly used in glass furnaces and regenerators but also used within blast stoves and blast furnaces.
