DXCQ1 Type Inert Alumina Ceramic Ball

Ceramic ball are widely used in the industry of petroleum, chemical, chemical fertilizer, natural gas, environmental protection and so on. Ceramic ball have the features of high intensity, high chemical durability and heat stability, which can resist the corrosion of  high temperature, high pressure, acid, alkali, salt as well as all kinds of organic solvents. Ceramic ball can also be used as catalyst's supporting and cladding material in reactor, which can buffer the impact for catalyst produced by liquid and gas entering into reactor, protect the catalyst and improve the distribution of liquid and gas in reactor.
