Introduction of inert alumina ceramics balls Inert alumina ceramics balls is widely used in petrochemical, chemical, metallurgical, gas and environmental protection, etc, used as covering and supporting material of catalyst in reaction vessel and packing in tower. It has the feature of high temperature and pressure resistance, low water absorption, and stable chemical performance. It can not only resist the corrosion of acid, alkali and other organic solvent, but also the temperature change in production ***** main role of inert ceramic ball is to increase the distributing spot of gas or liquid, also support and protect the activated catalyst with low strength. Our company according to the different content of Al2O3 ceramics ball, divided into the following several kinds of porcelain, specifications and technical indexes as follow: Specifications and diameter error of Inert alumina ceramics balls Diameter(mm) Φ3, 6, 9 Φ*3, *6 Φ*9, *5 Φ*0, *8 Φ*0 Φ*5, *5 Diameter error �1.0 �1.5 �2.0 �2.5 �3.0 �3.5 Other specifications are available produced according to customers’requirements.
