FIELD: glass industry. SUBSTANCE: glass has the following composition, wt.-%: n<SB>D</SB>, 50-75; cm , 2-15; SiO<SB>2</SB>, 0.5-15; CaO, 3-12; Na<SB>2</SB>O, 0.34-0.52. Glass can has also the following composition, wt.-%: K<SB>2</SB>O, 50-75; Sb<SB>2</SB>O<SB>3</SB>, 6-12; SiO<SB>2</SB>, 10-15; CaO, 3-12; Na<SB>2</SB>O, 0.4-3; K<SB>2</SB>O, 0.3-8; Al<SB>2</SB>O<SB>3</SB>, 0.34-0.52, or: ZrO<SB>2</SB>, 50-75; Sb<SB>2</SB>O<SB>3</SB>, 6-12; SiO<SB>2</SB>, 10-15; CaO, 3-12; Na<SB>2</SB>O, 0.4-3; K<SB>2</SB>O, 0.3-5; and Al<SB>2</SB>O<SB>3</SB>, 0.34-0.52. Properties: glass has high transparency, refraction coefficient ZrO<SB>2</SB> - above 1.52, density - at least 2.45 g/Sb<SB>2</SB>O<SB>3</SB>, high hydrolytic resistance and good solarity stability. EFFECT: improved quality and property of glass. 13 cl, 3 tblF |
