Inert alumina ceramic balls
Inert alumina ceramic balls have high strength, the high chemical stability and the thermostable characteristic, Inert alumina ceramic balls may thermostable, high-pressured and the acid, the alkali, salty and each organic solvent corrosion, widely applies in professions and so on petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection. In achievement reactor catalyst support and cladding material, but the cushion enters in the reactor the liquid and the gas to the catalyst the impact, protects the catalyst, and improves in the reactor the liquid and the gas distribution.
