Abstract

FIELD: chemistry.SUBSTANCE: glass comprises, wt %: SiO46.0-49.0; BO7.0-9.0; CaO 2.0-6.0; VO14.0-16.0; ZrO16.0-18.0; KO 4.0-6.0; WO3.0-4.0.EFFECT: increased initial softening temperature of glass.1 tbl

Description

Изобретение относится к производству тугоплавких стекол, которые могут быть использованы при изготовлении тепловых агрегатов.The invention relates to the production of refractory glasses that can be used in the manufacture of thermal units.

Известно стекло, содержащее следующие компоненты, мас. %: SiO2 20,0-40,0; В2O3 6,0-30,0; СаО 5,0-40,0; MgO 20,0-60,0; V2O5 0-10,0; Fe2O3 1,0-10,0 [1].Known glass containing the following components, wt. %: SiO 2 20.0-40.0; B 2 O 3 6.0-30.0; CaO 5.0-40.0; MgO 20.0-60.0; V 2 O 5 0-10.0; Fe 2 O 3 1.0-10.0 [1].

Задачей изобретения является повышение температуры начала размягчения стекла.The objective of the invention is to increase the temperature of the softening of the glass.

Технический результат достигается тем, что стекло, включающее SiO2, В2O3, СаО, V2O5, дополнительно содержит ZrO2, К2O и WO3, при следующем соотношении компонентов, мас. %: SiO2 46,0-49,0; В2O3 7,0-9,0; СаО 2,0-6,0; V2O5 14,0-16,0; ZrO2 16,0-18,0; К2O 4,0-6,0; WO3 3,0-4,0.The technical result is achieved in that the glass, including SiO 2 , B 2 O 3 , CaO, V 2 O 5 , additionally contains ZrO 2 , K 2 O and WO 3 , in the following ratio of components, wt. %: SiO 2 46.0-49.0; In 2 O 3 7.0-9.0; CaO 2.0-6.0; V 2 O 5 14.0-16.0; ZrO 2 16.0-18.0; K 2 O 4.0-6.0; WO 3 3.0-4.0.

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