Description
Изобретение относитс к составам стекол, используеьвлх дл получени стеклокристаллических цементов. Известен состав стекла дл стеклокристаллического цемента Cl, содержащий , вес. %: SiO 30-50; PbO 2040; ZnO 8-15; В,0з 5-15; МаО + LijO 7-10; 2,5-3,5. Указанный состав невозможно ticпользовать дл соединени материков имеющих ТКЛР в пределах 40-60- 1(Г 1/С Температура кристаллизации стекла . Наиболее близким к предлагаемому вл етс стекло дл получени стеклокристаллического цемента 23 содержащее , вес. %: ВгОз 10-20; РЬО 55-7.0 ZnO 10-20; Т(0г 4-15; не более Ю; MbjOj не более 5, Состав дает возможность получатб вакуумноплотные соединени стекла с монокристаллическими материалами,имею щими ТКЛР 4 О - 6 О 10 1 /С. Однако рабоча температура при получении спа сравнительно высока, вследствие чего происходит выгорание просветл ющего покрыти на монокриста.ллических мате . риалах, например покрыти ZnS, испол зуемого дл просветлени монокристад лических, прозрачных в области 8-14 мкм материалов. Кроме того, в процессе химической обработки из-за недос ,таточной химической стойкости указанного состава, происходит разрушение спа и, таким образом, нарушаетс его вакуумноплотность. Цель изобретени -снижение температуры кристаллизации и повышение кислотостойкости. Указанна цель достигаетс тем, что стекло дл стеклокристалЛического цемента, BKjno4aKMaee РЬО, , ZnO, N62,05, TiOa, дополнительно содержит Bi( PI Off. , при следующем соотношении компонентов, вес. %: РоО 55-60; 13-15; ZnO 10-15 Nb, 0,0,1-0,5; Т 162.8-12Bi O 2-5-, Р„0у 0,1-1; .0,5-1,5; 0,5-3. Разработанное стекло дл получени стеклокристаллического цемента вл етс технологичным дл варки, (в процессе варки добавл ют МНдЫО 0,5-5 вес. %) так как не происходит его кристаллизации во врем варки и выработки/ а также восстановление окислов свинца до металлического, Полученный состав размельчают до размеров частиц, проход щих в сито /FIELD OF THE INVENTION The invention relates to glass formulations used to produce glass-ceramic cements. Known glass composition for glass-ceramic cement Cl, containing, by weight. %: SiO 30-50; PbO 2040; ZnO 8-15; В, 0з 5-15; MaO + LijO 7-10; 2.5-3.5. This composition cannot be used for the connection of continents with TCLE within 40-60-1 (G 1 / C Glass crystallization temperature. The closest to the present invention is glass for the preparation of glass-ceramic cement 23 containing, wt.%: BrOz 10-20; PHO 55 -7.0 ZnO 10–20; T (0g 4–15; no more than 10; MbjOOj, no more than 5; The composition makes it possible to obtain vacuum-tight joints of glass with single-crystal materials having a TCLE 4 O – 6 O 10 1 / C. upon receipt of the spa is relatively high, resulting in a benefit The antireflection coating on monocrystalline mate rials, such as ZnS coatings, is used to clarify monocrystalline materials that are transparent in the region of 8-14 µm. In addition, during chemical treatment due to inadequate chemical stability of this composition, the destruction of the spa occurs and, thus, its vacuum density is disturbed. The purpose of the invention is to lower the crystallization temperature and increase the acid resistance. This goal is achieved by the fact that glass for glass-ceramic cement, BKjno4aKMaee PHO, ZnO, N62.05, TiOa, additionally contains Bi (PI Off., In the following ratio of components, wt.%: PoO 55-60; 13-15; ZnO 10-15 Nb, 0.0.1-0.5; T 162.8-12Bi O 2-5-, Р „0u 0.1-1; .0-1-1.5; 0.5-3. Developed the glass for the production of glass-ceramic cement is technological for cooking, (during the process of cooking, 0.5–5 wt.% MNDYO is added), since it does not crystallize during the cooking and generation, and the reduction of lead oxides to metal, the resulting composition is crushed d particle sizes extending in sieve /
10000 отв/см2 и смешивают с биндером до сметанообраэной консистенции. I Изготовленный таким образом стеклокристаллический цеМент (ситаллоце. ) примен ют в качестве промежу|точного сло между стеклом и моно )ристаллическими материалами, провод т его сушку при 40-60 с и далее термообработку (кристаллизации)в печи при 450-460 С.10,000 dv / cm2 and mixed with binder to a creamy consistency. I The glass ceramic cement thus produced (cellulose.) Is used as an intermediate layer between glass and mono-crystalline materials, is dried at 40-60 s and then heat treated (crystallized) in an oven at 450-460 C.
СИталлоцемент имеет хорошую, ад1гезию к стеклу и мо окристаллическим материалам.Cement-cement has good adhesion to glass and my-crystalline materials.
