Since alumina products have good high temperature properties and low price, they have found a wide application.
Corundum brick with high purity, high density and good properties is widely used in large blast furnaces and ladles. It has achieved a good result. It is the ideal lining material in the ammonia plant, gasifiers and crackers.
Corundum brick with good high temperature stability is preferred in the linings of vaious ultra-high temperature furnaces such as sintering furnace, molybdenum wire furnace, tungsten steel furnace, diffusion furnace, ceramic metal stove and molybdenum silicide electric stove.
Alumina hollow ball products and fiber products belong to high temperate energy-saving products. Since it has a low density, low thermal conductivity, it is the ideal lining material for saving energy and reducing consumption.
Precision alumina ceramics can be made into crucibles and gaskets for the smelting or purification of non-ferrous, rare and precious metals, high temperature furnace tubes, thermocouple protection tube, the insulating ceramic tube, laser tube, rectifier tube, transparent sodium lamp tube, radomes, microwave devices, pain sodium battery shell, gas purifier and spark plug.
Alumina ceramics can be made into wear-resistant, corrosion-resistant materials such as liquid metal filters, high temperature ceramics for chemical analysis and chemicals and textile industry machinery parts, such as seals, valves, piston pumps, petrochemical the catalyst carrier.
Alumina ceramics can be used in atomic energy reactor insulating sheet, artificial joints and artificial teeth in the bioengineering.
Due to the high hardness of corundum materials, second only to diamond, they are good is a good wear-resistant materials. they can be made into various cutting tools, abrasive materials, drawing dies, sita fiber guide wheel, mill prototype disc,high temperature wear-resistant bearings, Ball mill liners, grinding media balls and high temperature burner nozzles.
