PRODUCTION OF FORMED CERAMIC ARTICLE

摘要

PURPOSE:To obtain a forming for the production of a ceramic article having complicate shape and required to have high dimensional accuracy with few forming steps in a short time. CONSTITUTION:Slurry is produced by mixing 100 pts.wt. of inorganic powder composed of 50-97wt.% (preferably 70-90wt.%) of ceramic powder and 3-50wt.% (preferably 10-30wt.%) of rho-alumina powder with 15-50 pts.wt. (preferably 18-30 pts.wt.) of water. The slurry is injection molded into a non-water absorbing mold heated at 30-100 deg.C. The particle diameter of the above rho-alumina is 0.1-10mum.
