Alumina Ceramic:
Activated alumina has a selective adsorption power for gases, water vapor and certain liquids. After the adsorption is saturated, the water can be removed by heating at about 175-315 ° C for reactivation. Adsorption and reactivation can be performed multiple times. In addition to being used as a desiccant, it can also adsorb vapors of lubricating oil from contaminated oxygen, hydrogen, carbon dioxide, natural gas, and the like. It can also be used as a catalyst and catalyst carrier and a chromatography analysis carrier.
Activated Alumina Under certain operating conditions and regeneration conditions, the product has a drying depth of up to -70 degrees below the dew point temperature.
Ceramic effect
Alumina is divided into calcined alumina and ordinary industrial alumina. Calcined alumina is an essential raw material for producing antique bricks, while industrial alumina can be used to produce microcrystalline stone. In traditional glaze, alumina is often used for whitening. Since antique bricks and microcrystalline stones have been favored by the market, the amount of alumina is also increasing year by year.
Therefore, Alumina Ceramics came into being in the ceramic industry. Alumina ceramics is a kind of ceramic material with Al2O3 as the main raw material and corundum as the main crystalline phase. Because of its high mechanical strength, high hardness, high frequency dielectric Excellent overall technical performance such as low loss, high temperature insulation resistance, good chemical resistance and thermal conductivity.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
