Description

Изобретение относится к производству стекол, используемых, преимущественно, в электротехнике для создания покрытий различного назначения.The invention relates to the production of glasses used mainly in electrical engineering to create coatings for various purposes.

Известно легкоплавкое стекло, содержащее, мас.%: PbO 57,0-84,5; В2О3 4,0-5,0; GeO2 3,0-19,0; ТеО2 4,5-36,0 [1].It is known fusible glass containing, wt.%: PbO 57.0-84.5; B 2 O 3 4.0-5.0; GeO 2 3.0-19.0; TeO 2 4.5-36.0 [1].

Задача изобретения состоит в повышении температуры оплавления стекла.The objective of the invention is to increase the melting temperature of the glass.

Технический результат достигается тем, что легкоплавкое стекло, включающее PbO, GeO2 и В2О3, дополнительно содержит CeO2 и Na2O, причем компоненты находятся при следующем соотношении, мас.%: PbO 50,0-52,0; GeO2 3,0-4,0; В2О3 34,0-38,0; СеО2 1,0-5,0; Na2O 5,5-7,0.The technical result is achieved in that the low-melting glass including PbO, GeO 2 and B 2 O 3 additionally contains CeO 2 and Na 2 O, the components being in the following ratio, wt.%: PbO 50.0-52.0; GeO 2 3.0-4.0; B 2 O 3 34.0-38.0; CeO 2 1.0-5.0; Na 2 O 5.5-7.0.

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