(1) IntroductionThe inert alumina ceramic ball is broadly utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas, and environmental protection etc. There are lots of merits for it, for instance, the stronger resistance to high temperature and high pressure, lower ratio of the moisture absorbing, more stable chemical properties, and so on. It is capable of enduring the corrosion of acid, alkali, and organic solvent. In addition, it can also bear the rapid transitions of temperature during the operation. In fact, its principal functions are to accelerate the distribution of gas or liquid, and support or protect the active catalyst, which especially has the relevantly lower mechanical strength.¡¡¡¡(2) Chemical Compositions
