Description
Изобретение относится к производству стекол, используемых, преимущественно, в электронной и радиотехнической промышленности.The invention relates to the production of glasses used mainly in the electronic and radio industries.
Известно легкоплавкое стекло, содержащее, мас. %: PbO 75,6-76,4; В2О3 13,7-14,3; SiO2 3,0-5,0; ZrO2 3,5-4,5; Nd2O3 0,8-1,2 [1]. Температура размягчения такого стекла 365-370°C.Known fusible glass containing, by weight. %: PbO 75.6-76.4; B 2 O 3 13.7-14.3; SiO 2 3.0-5.0; ZrO 2 3.5-4.5; Nd 2 O 3 0.8-1.2 [1]. The softening temperature of this glass is 365-370 ° C.
Задача изобретения состоит в уменьшении количества дорогостоящего и токсичного PbO при сохранении температуры размягчения стекла.The objective of the invention is to reduce the amount of expensive and toxic PbO while maintaining the softening temperature of the glass.
Технический результат достигается тем, что легкоплавкое стекло, включающее PbO, В2O3, SiO2, Nd2O3, дополнительно содержит GeO2, причем компоненты находятся при следующем соотношении, мас. %: PbO 62,2-64,8; В2O3 17,0-21,0; SiO2 6.0-7,0; Nd2O3 0,8-1,2; GeO2 9,0-11,0.The technical result is achieved in that the low-melting glass, including PbO, B 2 O 3 , SiO 2 , Nd 2 O 3 , additionally contains GeO 2 , and the components are in the following ratio, wt. %: PbO 62.2-64.8; B 2 O 3, 17.0-21.0; SiO 2 6.0-7.0; Nd 2 O 3 0.8-1.2; GeO 2 9.0-11.0.
В таблице приведены составы стекла.The table shows the compositions of glass.
Варку стекла проводят в электропечах в окислительной среде.Glass is melted in an electric furnace in an oxidizing environment.
