METHOD TO PRODUCE FLAT GLASS-CRYSTAL MATERIAL Russian patent published in 1995 - IPC

Abstract RU 2044699 C1

FIELD: construction materials industry. SUBSTANCE: production of flat glass-crystal material of silicate melt provides for moulding and crystallization in one temperature zone on melted base with protecting melted layer. Special gravity of silicate melt is less than special gravity of corresponding protecting layer and base by 1.01-1.3 and 1.3-4 fold and temperature of mass crystallization is higher than temperature of protective layer flowing and temperature of base melting correspondingly by 1.01-1.7 and 1.01-1.2 fold. EFFECT: improved quality of surface, decreased production costs. 1 tbl
