Введение ВаО позвол ет получить хрусталь смешанного типа, т.е. с уменьшенным содержанием дефицитной РЪО, не ухудша физико-химических свойств.The introduction of BaO allows to obtain a mixed-type crystal, i.e. with a reduced content of deficient PbO, without compromising physical and chemical properties.
Добавка А g Oj способствует снижению улетучивани свинецсодержащих компонентов и тем самым повышает однородность стекпа и его оптические свойства .Additive A g Oj helps to reduce the volatilization of lead-containing components and thereby improves the uniformity of the glass and its optical properties.
Наличие нового сочетани обесцвечиватепей: HiO, ЕГ2О,, СеО ипи А$20} составе хрустапей смешанного типа -дает возможность получить нейтральный цвет в сочетании с высокой-светопрозрачностью при повышенном содержании крас щих примесей (0,О25-0,О8%).The presence of a new bleach blend: HiO, EG2O ,, SEO ipi A $ 20} of mixed-type crisps gives an opportunity to get a neutral color in combination with high translucency with an increased content of coloring impurities (0, O25-0, O8%).
Одновременное, введение NiO и Ег О позвол ет достигнуть компенсации эепеного цвета при меньших количествах i%O., в стекле и тем самым значительно снизить себестоимость стекла.The simultaneous introduction of NiO and ErO makes it possible to achieve compensation of the color with smaller amounts of i% O. in the glass and thereby significantly reduce the cost price of the glass.
Стекло получают по обычной технологии .Glass is produced by conventional technology.
