Изобретение отно ситс к составам стекол, нримеи емых, например, в онтическом приборостроении .The invention relates to glass formulations used, for example, in ontic instrument making.
Известные стекла, включаюндие SiOa, AljOj, Ре2Оз, СаО, MgO и TiO2 и при.меи емые в отражающей оитике, характеризуютс хорошей отражательной сиособностью и термостойкостью .Known glasses, including SiOa, AljOj, Fe2O3, CaO, MgO, and TiO2 and added in reflective coating, are characterized by good reflectivity and heat resistance.
Однако высокий коэффициент термического расширени известного стекла вызывает искажение изображени при температурных воздействи х .However, the high thermal expansion coefficient of the known glass causes distortion of the image during temperature effects.
Цель Изобретени - повысить коэффициент отражени и снизить коэффициент термического расширени .The purpose of the invention is to increase the reflection coefficient and reduce the coefficient of thermal expansion.
Достигаетс это тем, что стекло содержит указанные компонепты в следующих количествах , вес. %: SiO. 59-60; АЬОз 18,2-19,2; РегОз 10,9; СаО 1,04-1,05; MgO 5-7,2; TiOa 1,6-1,7 и, кроме того, F 3-3,5.This is achieved by the fact that the glass contains these components in the following amounts, wt. %: SiO. 59-60; ABOZ 18.2-19.2; Regoz 10.9; CaO 1.04-1.05; MgO 5-7.2; TiOa 1.6-1.7 and, in addition, F 3-3,5.
Стекло указанного состава по микротвердости и устойчивости к температурным воздействи м превосходит известное, а по отражательной способности почти не уступает ему.The glass of this composition in microhardness and resistance to temperature effects exceeds the known, and in reflectivity it is almost as good as it is.
Стекло характеризуетс следующими свойствами:Glass has the following properties:
