Description
Изобретение относитс к стекольной промышленности , в частности к изготовлению стекла, пригодного дл сортовой посуды и изделий декоративного назначени . Целью изобретени вл етс повышение показател преломлени . Стекла синтезируют в газопламенной печи в трехлитровых тигл х. Окислы ввод т через Ю следующие сырьевые материалы: SiOj, , . кварцевый песок; AljOj через глинозем; MgO через окись магни ; ZnO через цинковые белила; ВаО через углекислый барий; СаО через мел; CaF через флюорит. .15 11881 5 1 Все компоненты шихты тщательно перемешивают , засыпку ведут при 1380° в три према. В течение часа температуру поднимают до 1420 С, варку ведут 4 ч. Составы синтезированных стекол (мас.%) и их свойства представлены в таблице. Показатель преломлени определ ют иммерсионным методом и дл составов 1-7 он равен, соответственно 1,620; 1,618; 1,628; 1,625; 1,613; 1,619; 1,624. Химическую стойкость (гидрол. класс) определ ют вьццелачиванием поверхности зерен стекла воздействием воды (дл состаBOB 1-7 химическа стойкость равна 11) The invention relates to the glass industry, in particular to the manufacture of glass suitable for high-grade tableware and articles of decorative purpose. The aim of the invention is to increase the refractive index. Glasses are synthesized in a gas-flame furnace in three-liter crucibles. Oxides are introduced through the following raw materials: SiOj,,. quartz sand; AljOj through alumina; MgO through magnesia; ZnO through zinc white; BaO through barium carbonate; CaO through chalk; CaF through fluorite. .15 11881 5 1 All components of the mixture are thoroughly mixed, filling is carried out at 1380 ° in three prema. Within an hour, the temperature is raised to 1420 ° C, cooking takes 4 hours. The compositions of the synthesized glasses (wt.%) And their properties are presented in the table. The refractive index is determined by the immersion method and for compounds 1-7, it is equal, respectively, to 1.620; 1.618; 1,628; 1.625; 1.613; 1.619; 1.624. The chemical resistance (hydrol. Class) is determined by the enduring of the surface of the glass grains by exposure to water (for a BOB 1-7 chemical resistance is 11)
