Abstract
PURPOSE:To obtain a building material of crystallized glass having both luster of glass and strength of ceramic, by molding mixed powder of specific low- softening glass and specific high-softening glass, sintering and crystallizing. CONSTITUTION:Low-softening glass powder which comprises 60-80wt.% SiO2, <=15wt.% Al2O3, 5-15wt.% CaO, 10-20wt.% Na2O+K2O, has >=90wt.% sum of the above-mentioned components and a particle size constitution of >=90wt.% particles with <=200 meshes is blended with high-softening glass powder which comprises 35-55wt.% SiO2, 5-20wt.% Al2O3, 20-50wt.% CaO, 3-10wt.% MgO, has >=90wt.% sum of the above-mentioned components and a particle size constitution of >=90wt.% particles with <=200 meshes to give mixed powder consisting of 80-40wt.% of the former and the rest of the latter, which is molded. Then the molded article is heat-treated, sintered and crystallized to mainly precipitate CaO.SiO2 crystal and CaO.Al2O3.SiO2 crystal.
