Description

Изобретение относится к технологии силикатов, а именно к производству стекол, которые могут быть использованы для изготовления лабораторной посуды.The invention relates to the technology of silicates, namely the production of glasses that can be used for the manufacture of laboratory glassware.

Известно стекло, содержащее следующие компоненты, мас.%: SiO2 98,0-99,5, SnO2 0,5-2,0 [1].Known glass containing the following components, wt.%: SiO 2 98,0-99,5, SnO 2 0,5-2,0 [1].

Задачей изобретения является повышение термостойкости стекла.The objective of the invention is to increase the heat resistance of glass.

Технический результат достигается тем, что стекло, включающее SiO2 и SnO2, дополнительно содержит по крайней мере один компонент из группы BeO, MgO, СаО при следующем соотношении компонентов, мас.%: SiO2 74,5-83,0, SnO2 0,5-2,0, по крайней мере один компонент из группы BeO, MgO, СаО 15,0-25,0.The technical result is achieved in that the glass, including SiO 2 and SnO 2 , additionally contains at least one component from the group of BeO, MgO, CaO in the following ratio of components, wt.%: SiO 2 74.5-83.0, SnO 2 0.5-2.0, at least one component from the group of BeO, MgO, CaO 15.0-25.0.

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