Нёдостагком стекла вл етс то, что оно обладает сравнительно низким коэффициентом преломлени - 1,5231 ,325, т.е. не отвечает требовани м, предъ вл емым к свет отехническим стеклам дл бытовьЬг светильников, так как не дает необходимого оптического эстетического эффекта.A stepless glass is that it has a relatively low refractive index of 1.5231, 325, i.e. It does not meet the requirements imposed on light from the original glass for household lighting, as it does not provide the necessary optical aesthetic effect.
Наиболее близким к изобретению вл етс стекло, включающее следующие компоненты, вес.%: SiO 54-57; ВаО 19-22; ZtiO 2-4; Na-jO 4т6; 1416; Sb-iO-, 0,56-0,60; Ег«0а--0,020 ,08 2.Closest to the invention is glass, comprising the following components, wt%: SiO 54-57; BaO 19-22; ZtiO 2-4; Na-jO 4t6; 1416; Sb-iO-, 0.56-0.60; Ег «0а - 0,020, 08 2.
Коэффициент преломлени известного стекла составл ет 1,5375-1,5380, светопропускание 92,8-94,-0%j-1 т сырье;вых материалов стоит 508,68 руб.The refractive index of the known glass is 1.5375-1.5380, the light transmittance is 92.8-94, -0% j-1 ton raw materials; the cost of these materials is 508.68 rubles.
Целью изобретени вл етс снижение себестоимости при сохранении показател преломлени и светопропускани .The aim of the invention is to reduce the cost while maintaining the refractive index and light transmission.
Поставленна цель достигаетс тем, что стекло, включающее SiO, ВаО, ZnO, , , , , дополнительно содержит СаО, AlgOj и один компонент из группы TiO, СеО при следующем соотношении компонентов , мас.%;This goal is achieved by the fact that glass including SiO, BaO, ZnO,,,, additionally contains CaO, AlgOj and one component from the group TiO, CeO in the following ratio of components, wt.%;
