Description
Известно, что безборное, химически и термически стойкое, цирконовое стекло дл изготовлени химической посуды, содержащее 65- 70% кремнезема, 2-5% двуокиси циркони , 13-16,5% суммы окислов натри и кали , до 12% окиси кальци и около 0,5% окиси алюмини , требует повышенной температуры варки, что затрудн ет его производство .It is known that bezborne, chemically and thermally resistant, zircon glass for the manufacture of chemical glassware, containing 65-70% silica, 2-5% zirconium dioxide, 13-16.5% of the amount of sodium and potassium oxides, up to 12% calcium oxide and about 0.5% alumina requires an elevated cooking temperature, which makes it difficult to produce.
Большим количеством опытов установлено, что введение в вышеуказанный состав стекла, в пор дке замешени окиси кальци , окиси магни до 2-5% и увеличение содержа-миЯ окиси алюмини до 2-5%,-A large number of experiments have shown that the introduction of glass into the above composition, in the order of mixing calcium oxide and magnesium oxide up to 2-5% and an increase in the content of aluminum oxide up to 2-5%, -
понижают температуру варки стекла и этим облегчают его производство, при этом щелочеустойчивость стекла повышаетс .lower the temperature of glass melting and thereby facilitate its production, while the alkali resistance of glass increases.
Предмет изобретени Стекло дл изготовлени химической посуды и аппаратуры, содержащее 64-70% кремнезема, 2-5% двуокиси циркони , 13-16% суммы окислов натри и кали , а также окись кальци , окись алюмини и окись магни , отличающеес те., что, с целью повышени щелочеустойчивости стекла, в него вход т окиси кальци 4-7,5°/о, окиси алюмини 2-5/о н окиси магни 2-5%.The subject of the invention Glass for the manufacture of chemical glassware and apparatus containing 64-70% silica, 2-5% zirconium dioxide, 13-16% of the sum of sodium and potassium oxides, as well as calcium oxide, alumina and magnesia, which , in order to increase the alkali resistance of glass, it includes calcium oxide 4-7.5 ° / o, aluminum oxide 2-5 / o of magnesium oxide 2-5%.
