PRODUCTION METHOD OF GRANULE, PRODUCTION METHOD OF POROUS CERAMIC SINTERED COMPACT AND POROUS CERAMIC SINTERED COMPACT

摘要

PROBLEM TO BE SOLVED: To provide a production method of a granule, a production method of a porous ceramic sintered compact and the porous ceramic sintered compact.;SOLUTION: A slurry having a ceramic powder(an alumina powder, etc.), a granule for making a pore (a cross linked polymethylmethacrylate granule, etc.) and a dispersion medium(water, etc.), is supplied to an atomizer disk rotating at 12,000 rpm or above, and is sprayed from an opening part to be dried to produce the granule. The granule is press molded and calcined to produce the porous ceramic sintered compact. Especially, the porous ceramic sintered compact having the permeability of 5×10^-7-5×10^-6 mm² and the bending strength of 20-60 MPa can be produced.;COPYRIGHT: (C)2007,JPO&INPIT
