In some industries, corundum brick has a very important role. In the work process, the raw materials used are abundant, and the supply is very convenient, in terms of manufacturing process, either by production technology of traditional refractory materials production producing corundum refractory materials, can also use the method of spun out of the traditional ceramic to produce special refractory materials, namely high temperature ceramic, So go through half a century of development and production, now production technology becomes mature gradually, and variety is also growing, has become the most widely application scope of refractory materials, its purposes are as follows:
Because of the high temperature insulation, may be used as the set of thermocouple wire pipe and protection, the insulation porcelain used in atomic reactor, and other high temperature insulation parts, such as platinum - rhodium thermocouple even up to 1720 ℃ is airtight.
The gas tightness of corundum products is good, it is rigor and airtight even if under high temperature. Therefore is widely used in electric vacuum, for example, use corundum to make various large tube shell, dual-in-line package in solid microcircuit dual-in-line package to sealing shell.
6. Corundum insulation materials, such as corundum light brick, alumina hollow ball and fiber products, widely used in various high temperature furnaces of furnace wall and furnace top, high temperature resistant and heat preservation.
