Description

Изобретение относится к области технологии силикатов и касается составов стекла, которое может быть эффективно использовано для изготовления световых рассеивателей.The invention relates to the field of technology of silicates and relates to glass compositions, which can be effectively used for the manufacture of light diffusers.

Известно стекло, включающее, мас.%: SiO2 54,0-60,0; CaO 11,0-19,0; Na2O4 0-6,0; K2O 7,0-10,0; B2O3 1,0-4,0; MgO 1,0-3,0; ZnO 4,0-10,0; Al2O3 1,0-5,0 [1].Known glass, including, wt.%: SiO 2 54,0-60,0; CaO 11.0-19.0; Na 2 O 4 0-6.0; K 2 O 7.0-10.0; B 2 O 3 1.0-4.0; MgO 1.0-3.0; ZnO 4.0-10.0; Al 2 O 3 1.0-5.0 [1].

Известно стекло, содержащее, мас.%: SiO2 69,65-73,15; CaO 7,2-9,5; Na2O 13,25-14,95; K2O 2,4-3,4; CeO2 1,5-2,5; Fe2O3 1,0-1,5 [2].Known glass containing, wt.%: SiO 2 69,65-73,15; CaO 7.2-9.5; Na 2 O 13.25-14.95; K 2 O 2,4-3,4; CeO 2 1.5-2.5; Fe 2 O 3 1.0-1.5 [2].

Целью изобретения является повышение показателя преломления стекла.The aim of the invention is to increase the refractive index of glass.

Цель достигается тем, что в состав стекла дополнительно вводят PbO, Cl', Se, при следующем соотношении компонентов, мас.%: SiO2 66,0-70,0; CaO 8,0-12,0; Na2O 8,0-12,0; K2О 3,0-5,0; CeO2 0,7-1,7; PbO 3,0-5,0; Cl' 0,1-0,2; Se 0,1-0,2.The goal is achieved by the fact that the composition of the glass is additionally introduced PbO, Cl ', Se, in the following ratio of components, wt.%: SiO 2 66,0-70,0; CaO 8.0-12.0; Na 2 O 8.0-12.0; K 2 O 3.0-5.0; CeO 2 0.7-1.7; PbO 3.0-5.0; Cl '0.1-0.2; Se 0.1-0.2.

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