PRODUCTION OF FOAMABLE CERAMIC MATERIAL, FOAMABLE CERAMIC MATERIAL, AND PRODUCTION OF FOAMED CERAMIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To enable to produce a foamable ceramic material capable of firing at a low temp. even by spray drying. ;SOLUTION: The low temp. firing is enabled by including a process for obtaining a sludge material by wet pulverizing a raw material containing a ceramic material, a foaming component, 1-10 wt.% alkali component per total weight of the raw material. and 0.5-5 wt.% organic dispersing agent per total weight of the raw material and a process for obtaining a foamable ceramic material composed of a granulated material by spray drying the sludge material and the granulation by the spray drying is excellently performed because the increase of the viscosity is suppressed by the organic dispersing agent though the alkali component, which has a defect of causing the increase of the viscosity, is contained.;COPYRIGHT: (C)2000,JPO
