PURPOSE:To facilitate the handling of unfired formed products by using a specific binder. CONSTITUTION:A material for porcelain is obtained by mixing a binder one or more selected from a high-temperature fired product of alpha-type tricalcium phosphate, tetracalcium phosphate, CaO-P2O5-SiO2 system and elevated- temperature fused product of CaO-P2O5-SiO2 system, with one or more selected from feldspar, clay, kaolin and mica. Then, 10 pts.wt. of the material are mixed with 2 to 5 pts.wt. of water, when needed, additionally an acid, such as phosphoric acid, a salt such as a phosphate salt, pigments or the like to form a slurry, then the base material is coated or impregnated with the slurry, cured and fired. |
