Description
Изобретение относитс к составам хрустальных стекол, предназначенных, дл производства бытовых и декоратив ных изделий. Известно , включающее РЬО, ВаО, ZnO, , N35,0, TiO,, , SiOjt, в следующих количествах, вес.ё: РЬО 0,1-12; ВаО 0,1-12; ZnO 5-10; 10-17; NajO 0,1-7; Ti020,1-2; 1-2, остальное SiO t1. Стекло имеет короткий интервал формовани . Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс стекло следующего состава, вес.: SiOj 60-66; СаО 0.,5-1.3; Naj,0 1-6; KjO 10-17; 1,0-1,2; РЬО 17-19; ZnO 1-3 С23 Это стекло обладает низкой химической устойчивостью (.IV гидролитический .класс). Кроме того, эти стекла характеризуютс плохими выработоч ными свойствами. Цель изобретени - повышение химической устойчивости и улучшение выработочных свойств. Цель достигаетс тем, что стекло,. включающее SiO, СаО, , , ,содержит указанные компоненты в следующих количествах, мас.%: СаО 0,1-5 12-18 NajO 1-7 BiOj 0,1-i SiOj Остальное Состав описываемого стекли может . содержать с целью повышени коэффициента преломлени , мас.%: РЬО 2-8 или ВаО 6-20. В табл, 1 приведены предлагаемые составы стекол. В табл. 2 приведены свойства предлагаемых стекол. Издели - из описываемого стекла не уступают издели м из свинцового хрустал по белизне, светопрозрачности и игре света на гран х.This invention relates to crystal glass compositions intended for the manufacture of household and decorative articles. It is known, including PbO, BaO, ZnO,, N35.0, TiO ,,, SiOjt, in the following amounts, wt.ё: PBO 0.1–12; BaO 0.1–12; ZnO 5-10; 10-17; NajO 0.1-7; Ti020.1-2; 1-2, the rest is SiO t1. The glass has a short forming interval. The closest in technical essence and the achieved result to the invention is glass of the following composition, weight: SiOj 60-66; CaO 0., 5-1.3; Naj, 0 1-6; KjO 10-17; 1.0-1.2; PWO 17-19; ZnO 1-3 C23 This glass has low chemical resistance (.IV hydrolytic class). In addition, these glasses are characterized by poor working properties. The purpose of the invention is to increase chemical resistance and improve the working properties. The goal is achieved by the fact that the glass ,. including SiO, CaO,,,, contains these components in the following amounts, wt.%: CaO 0.1-5 12-18 NajO 1-7 BiOj 0.1-i SiOj Else The composition of the described glass can. contain in order to increase the refractive index, wt.%: PHO 2-8 or BaO 6-20. Table 1 shows the proposed glass compositions. In tab. 2 shows the properties of the proposed glass. Products - from the described glass are not inferior to products made of lead crystal in whiteness, translucency and play of light on the edge.
