Inert CERAMIC BALLS stable molecular structure, acid and alkali - resistant, heat-resistance, good thermal stability - details see: https://www.machineto.com/inert-ceramics-ball-industrial-ceramic-ball-10368379

inert ceramic ballsis used in catalyst bed support and tower packing.Inert Alumina Ball is widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection etc. With functions as covering and supporting materials for catalyst in reactors and packing for towers. The main role of inert alumina ball is increasing the distribution of liquid and gas, holding and protecting the activated catalyst with low strength.
