Description
Изобретение относитс к составам стекол. Известно стекло, включающее Si02, , LaoOs. Цель изобретени - обеспечение температуры деформации до 1150-1180°С и снижение коэффициента термического расширени . Свойства предлагае.мого сте Достигаетс это тем, чтооно дополнительно содержит ВаО при следующем соотношении компонентов, вес. %: SiOa45-55 АЬОз15-25 ЬагОз3-25 ВаО5-30 а приведены в таблицеThe invention relates to glass compositions. Known glass, including Si02,, LaoOs. The purpose of the invention is to provide a temperature of deformation up to 1150-1180 ° C and a reduction in the coefficient of thermal expansion. The properties are proposed to the world. This is achieved by the fact that it additionally contains BaO in the following ratio of components, weight. %: SiOa45-55 ALOz15-25 lagos3-25 BaO5-30 and are given in the table
Технологи получени стекла обычна . В качестве сырь примен ютс Новоселовский кварцевый песок, окись алюмини , окись лантана и карбонат бари . Обжиг стекла производитс в электроиечах в интервале температур 950-1050° С.Glass technology is common. Novoselovsky quartz sand, alumina, lanthanum oxide and barium carbonate are used as raw materials. Glass firing is performed in electrofluids in the temperature range 950-1050 ° C.
