building materials industry, more particularly manufacture of glass granulate for preparing decorative and facing materials. SUBSTANCE: temperature of glass formation temperature reduced by 60-70 C not only decreases energy consumption for preparing decorative and facing material from granules manufactured from opacified glass, but also improves quality of decorative and facing material. Opacified glass comprises, wt.%: SiO2, 59.0-63.0; Al2O3, 3.6-4.0; CaO, 8.0-11.0; Na2O, 16.4-18.0; P2O5, 6.0-8.5; F2, 0.4-0.65; Fe2O3 0.1-0.15; SrO, 0.44-0.6; TiO2, 0.06-0.1. EFFECT: improved properties of the opacified glass. 1 tbl |
