Description

Известны стекла на основе двуокиси кремни , окиси бора, окиси алюмини , окиси свинца и фтора, которые в результате двухстадииной термической обработке по заданному дл  каждого из них режиму, кристаллизуютс  и из прозрачного тела превращаютс  в непрозрачное.Known glasses based on silica, boria, alumina, lead oxide and fluorine, which, as a result of a two-stage heat treatment according to the conditions set for each of them, crystallize and turn from opaque to opaque.

Особенностью таких стекол  вл етс  высокое сопротивление на изгиб (2000 кг/см) и высока  температура разм гчени  (1350)Предлагаемое стекло состоит из тех же компонентов, но вз тых в ином количестве, что значительно повышает упом нутые свойства полученного из него закристаллизованного материала.A characteristic feature of such glasses is high bending resistance (2000 kg / cm) and high softening temperature (1350). The offered glass consists of the same components, but taken in a different quantity, which significantly improves the aforementioned properties of the crystallized material obtained from it.

Состав стекла по весу следуюгций: SiO - 48-43%, АЬОз-22-27%, В2Оз-18-23%, РЬО -8-13%, F -2-6%.The glass composition by weight is as follows: SiO - 48-43%, ABOz-22-27%, B2Oz-18-23%, PHO -8-13%, F -2-6%.

Из сваренного стекла вышеприведенного состава вырабатывают издели  прессовкой- выдуванием, литьем, или другими методами затем с целью создани  центров кристаллизации выдерживают их при температуре около 800°, а потом подвергают термообработке при 1200° и выше с целью полной кристаллизации материала.From the welded glass of the above composition, products are produced by pressing-blowing, casting, or by other methods, then with the aim of creating crystallization centers, they are kept at a temperature of about 800 ° and then heat-treated at 1200 ° and above in order to fully crystallize the material.

Сопротивление на изгиб полученного закристаллизированного материала достигает 2500 кг/см, термостойкость- 1230°, температура разм гчени  - выше 1400°.The bending resistance of the obtained crystallized material reaches 2500 kg / cm, the heat resistance is 1230 °, and the softening temperature is above 1400 °.
