Description
Изобретение относитс к высокожелезистым стеклам, используемым в качестве облицовочного и химически стойко.го материала.FIELD OF THE INVENTION The present invention relates to high iron glasses used as a lining and chemically resistant material.
Известны высокожелезистые стекла, содержащие SiOz, АЬОз, РеаОз, FeO, СаО, MgO, КгО. Однако дл известного стекла характерна недостаточна химичеока стойкость, ограничивающа его применение.High-iron glasses containing SiOz, AO3, ReaO3, FeO, CaO, MgO, CgO are known. However, the known glass is characterized by insufficient chemical resistance, limiting its use.
Цель изобретени - повысить химическую стойкость и снизить коэффициент термического расширени высокожелезистых стекол.The purpose of the invention is to increase chemical resistance and reduce the coefficient of thermal expansion of high-iron glasses.
Это достигаетс тем, что стекло содержит компоненты в следующих количествах, вес. %: SiOs54-60This is achieved in that the glass contains components in the following amounts, weight. %: SiOs54-60

Дл /получени стекла данного состава беретс шихта, состо ща из 100 вес. ч. шлака никелевого производства, 20-40 вес. ч. кварцевого песка и 6-7 вес. ч. сульфата натри . Варка стекла проводитс при 1400-1420°С, формование изделий - при 1250-1300°С и отжиг -при 600°С.In order to obtain glass of this composition, a charge consisting of 100 wt. including slag nickel production, 20-40 weight. including quartz sand and 6-7 wt. including sodium sulfate. Glass melting is carried out at 1400-1420 ° C, products are molded at 1250-1300 ° C and annealed at 600 ° C.
Полученное стекло обладает следующими сзойствамк: Химическа стойкость по отношению:The resulting glass has the following properties: Chemical resistance against:
