摘要

A ceramic porous body for use in filtering molten metal is disclosed. The ceramic porous body has a three-dimensionally network cellular structure with a plurality of interconnected voids and is characterized by having a pore size of 25-35 pores per linear centimeter in optional cut area, a bulk specific gravity of 0.3-0.7, a porosity of 75-90%, and a pressure loss of 4.8-30.0 mm as a water-gauge pressure when passing air through the body of 1 cm thickness at a rate of 1 m/sec.
