Description
Изобретение относится к составам стекол с повышенным коэффициентом светопреломления, которые могут быть использованы в оптических приборах, а также для изготовления декоративно-художественных изделий.The invention relates to glass compositions with a high refractive index, which can be used in optical devices, as well as for the manufacture of decorative and artistic products.
Известно оптическое стекло, содержащее, мас.%: PbO 60,0-70,0; SiO2 5,0-15,0; GeO2 5,0-10,0; ZnO 10,0-15,0 [1].Known optical glass containing, wt.%: PbO 60,0-70,0; SiO 2 5.0-15.0; GeO 2 5.0-10.0; ZnO 10.0-15.0 [1].
Задача изобретения состоит в уменьшении количества дорогостоящего и токсичного PbO при сохранении показателя светопреломления.The objective of the invention is to reduce the amount of expensive and toxic PbO while maintaining a refractive index.
Технический результат достигается тем, что оптическое стекло, содержащее PbO, SiO2, GeO2, ZnO, дополнительно содержит СаО при следующем соотношении компонентов, мас.%: PbO 56,0-63,0; SiO2 10,0-17,0; GeO2 12,0-14,0; ZnO 6,0-8,0; СаО 5,0-9,0.The technical result is achieved in that the optical glass containing PbO, SiO 2 , GeO 2 , ZnO, additionally contains CaO in the following ratio of components, wt.%: PbO 56,0-63,0; SiO 2 10.0-17.0; GeO 2 12.0-14.0; ZnO 6.0-8.0; CaO 5.0-9.0.
В таблице приведены составы стекла.The table shows the compositions of glass.
Стекло может быть сварено при температуре 1380-1400°С в электропечах любой конструкции.Glass can be welded at a temperature of 1380-1400 ° C in electric furnaces of any design.
