Inert alumina ceramic ball (ICB)
is used as the covering, packing and supporting materials of the catalyst in reactors and columns in varied areas.Its strong resistance to the high temperature and high pressure, lower ratio of the moisture absorption, stable chemical properties, and its capacity of enduring the corrosion of acid, alkali, and organic solvent make it broadly utilized in petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection fields etc.Based on the alumina balls, we developed series of 38 different kinds and size of them with different alumina contains, the porous balls, and ceramic columns.
