Description

Изобретение относится к составам стекла, используемого для изготовления сортовой посуды, изделий декоративно-художественного назначения.The invention relates to compositions of glass used for the manufacture of long products, decorative and artistic products.

Известно стекло, содержащее, мас.%: SiO2 60,0-70,0; K2O 3,0-5,0; Na2O 10,0-15,0; B2O3 1,0-3,0; ZnO 4,0-5,7; Cds 1,0-2,0; Se 0,0-1,0; F' 0,1-1,0; по крайней мере два окисла из группы CaO, BaO, SrO 5,0-9,0 /1/.Known glass containing, wt.%: SiO 2 60,0-70,0; K 2 O 3.0-5.0; Na 2 O 10.0-15.0; B 2 O 3 1.0-3.0; ZnO 4.0-5.7; Cds 1.0-2.0; Se 0.0-1.0; F '0.1-1.0; at least two oxides from the group CaO, BaO, SrO 5.0-9.0 / 1 /.

Известно стекло, содержащее, мас.%: SiO2 70,0-75,0; CaO 4,96-14,9; Na2O 14,29-19,0; CdO 0,6-0,85; Se 0,13-0,3; S 0,08-0,12 /2/.Known glass containing, wt.%: SiO 2 70,0-75,0; CaO 4.96-14.9; Na 2 O 14.29-19.0; CdO 0.6-0.85; Se 0.13-0.3; S 0.08-0.12 / 2 /.

Цель изобретения - повышение показателя преломления света и снижение температуры варки стекла.The purpose of the invention is to increase the refractive index of light and reduce the temperature of glass melting.

Цель достигается тем, что в состав стекла дополнительно вводят Sb2O3 и PbO, при следующем соотношении компонентов, мас.%: SiO2 70,0-75,0; CaO 6,0-7,0; Na2O 4,0-5,0; CdO 8,0-12,0; Se 0,2-0,3; Sb2O3 0,1-0,2; PbO 5,7-6,7.The goal is achieved by the fact that Sb 2 O 3 and PbO are additionally introduced into the glass composition, in the following ratio of components, wt.%: SiO 2 70.0-75.0; CaO 6.0-7.0; Na 2 O 4.0-5.0; CdO 8.0-12.0; Se 0.2-0.3; Sb 2 O 3 0.1-0.2; PbO 5.7-6.7.

В таблице приведены составы стекла.The table shows the compositions of glass.
