Al2O3: from 20% to 90%
Size: from 6mm to 75mm
Ceramic Porous Ball developed on the basis of inert ceramic ball, owns one pore or several pores.
Compared with inert ceramic ball, it has great mechanical strength,good chemical and thermal stability.And also has larger surface area and free void which directly increased the dispersion and flux of the fluids and reduce the resistance.
Widely used in oil refinery, chemical, fertilizer, natural gas and environment protection industries.Instead of inert ceramic ball works as catalyst carrier, and praised by many users.
