METHOD FOR MANUFACTURING CERAMIC POROUS BODY AND COMPOSITION FOR MANUFACTURING SAID CERAMIC POROUS BODY

摘要

The present invention relates to a method for manufacturing a ceramic porous body, comprising: a step (S1) of mixing silica powder and zircon powder, having a mean particle size of 0.045 to 0.5 mm, and wax to prepare a ceramic mixture; a step (S2) of pouring the ceramic mixture into a mold to produce a molded form; and a step (S3) of sintering the molded form at a high temperature to manufacture a ceramic porous body. The ceramic porous body contains 50 to 80 wt % of the silica powder having a mean particle size of 0.1 to 0.5 mm relative to the total weight of the ceramic porous body. The method for manufacturing a ceramic porous body according to the present invention can enable the manufacture of a bulk-type ceramic porous body which has excellent dimensional stability and shape stability and which exhibits superior strength and excellent leaching characteristics.
