Description

Изобретение относится к области технологии силикатов, в частности к составам стекла, которое может быть использовано для изготовления смотровых окон тепловых агрегатов, изделий хозяйственно-бытового назначения.The invention relates to the field of technology of silicates, in particular to glass compositions, which can be used for the manufacture of viewing windows of thermal units, household products.

Известно стекло, содержащее SiO2, K2O, CaO, B2O3, а также другие компоненты [1].Known glass containing SiO 2 , K 2 O, CaO, B 2 O 3 , as well as other components [1].

Известно стекло следующего состава, мас.%: SiO2 56-66; Na2O 7,4-9,4; K2O 1,8-3,8; CaO 3-5; Na2SiF6 21,5-25,6; CoO 0,2-0,3 [2]. КТР такого стекла составляет (82-84)×10-7°С-1 термостойкость 263-268 °C.Known glass of the following composition, wt.%: SiO 2 56-66; Na 2 O 7.4-9.4; K 2 O 1.8-3.8; CaO 3-5; Na 2 SiF 6 21.5-25.6; CoO 0.2-0.3 [2]. The KTP of such a glass is (82-84) × 10 -7 ° C -1 heat resistance 263-268 ° C.

Целью изобретения является снижение коэффициента термического расширения и повышение термостойкости стекла.The aim of the invention is to reduce the coefficient of thermal expansion and increase the heat resistance of glass.

Цель достигается тем, что в состав стекла дополнительно вводят ZrO2 и B2O3 при следующем соотношении компонентов, мас.%: SiO2 60-66; K2О 3-4; CaO 3-5; CoO 0,3-1; ZrO2 15-20; B2O3 10,7-12.The goal is achieved by the fact that ZrO 2 and B 2 O 3 are additionally introduced into the glass composition in the following ratio of components, wt.%: SiO 2 60-66; K 2 O 3-4; CaO 3-5; CoO 0.3-1; ZrO 2 15-20; B 2 O 3 10.7-12.

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