What is the difference between high alumina bricks and clay bricks?
Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay, which is finely ground and then cast and shaped in the form of slurry by gas generation method or foam method, and then burned at 1300～1500℃. Sometimes industrial alumina can also be used to replace part of the bauxite clinker.

Sometimes industrial alumina can also be used to replace part of the bauxite clinker. It is used for masonry kiln lining and insulation, and parts without strong high-temperature molten material erosion and scouring effect. Direct contact with the flame, the surface contact temperature shall not be higher than 1350 ℃.
Lightweight clay bricks, heat-insulating refractories are refractories with high porosity, low bulk density and low thermal conductivity, heat-insulating refractories are also called lightweight refractories, which include heat-insulating refractory products, refractory fibers and refractory fiber products. Heat-insulating refractories are characterized by high porosity, generally 40% -85%; low bulk density below 1.5g/cm3; low thermal conductivity, generally below 1.0W (m.K). It acts as a heat-insulating material for industrial kilns, reduces heat loss from the kiln, saves energy, and reduces the quality of thermal equipment. Heat-insulating refractories mechanical strength, abrasion resistance and resistance to slag erosion is poor, not suitable for kiln load-bearing structure and direct contact with slag, charge, molten metal and other parts.
From the aluminum content, single weight, the use of temperature, there are differences in color. For example: 75 high alumina and 43 clay bricks, 75 single weight 4.5kg above. 43 of 3.65kg or so, the use of temperature 75 high alumina in 1520 or so, 43 of the brick 1430 or so, the color of 75 white, 43 of the yellow earth color. In short, there is a big difference.
