Description
Изобретение относитс к составу стекла, используемому в качестве электротехнического материала в .приборах специального назначени .The invention relates to a glass composition used as an electrical material in special purpose devices.
Известно, стекло, включающее Si02, Ре2Оз, СаО, MgO, ВаО, МпО, Na20, К20.It is known glass including Si02, Fe2Oz, CaO, MgO, BaO, MpO, Na20, K20.
Предлагаемое стекло обладает улучшенными выработочными и формовочными свойст;вами , а также повышенной механическойThe offered glass has improved working and molding properties, as well as enhanced mechanical

стекла. В результате этого резко возрастают механические свойства стекла и заметно уменьшаетс его хрупкость. Термообработкой стекол в интервале 500-680°С возможноglass As a result, the mechanical properties of glass dramatically increase and its brittleness is noticeably reduced. Heat treatment of glasses in the range of 500-680 ° C is possible
