Description

Изобретение относитс  к стеклам с высоким пропусканием рентгеновского излучени . Известно стекло марки С47-1(46) дл  изготовлени  стекл нных баллонов рентгеновских приборов, содержащее SiO2, ВгОз, АЬОз, ZnO, NaaO. Предлагаемое стекло позвол ет повысить пропускание ренгеновских лучей стекл нным баллоном и его электропрочность. Достигаетс  это тем, что используют стекло стекла: Коэффициент линейного расширени  а-10 1/°С48,5Температура разм гчени , °С Термостойкость, °С Температура, при которой удельное объемное сопротивление стекла равно 100 мом-см (Тк-100) не менее 220 5 10 15 20 25 ских потерь, tg6 -10 при частоте 10 гц42 Электропрочность, кв/мм260 Химическа  устойчивость, % потерь0,06 {I гидролитический класс) Пропускание рентгеновских лучей стекл нными баллонами с толщиной стенки 2,0 мм и 1,6 мм, изготовленными из описываемого стекла , увеличилось в 1,5 раза в сравнении с баллонами с той же толщиной стенки, но изготовленными из стекла марки С47-1. Стекло технологично и его можно варить в ванных печах периодического действи . Предмет изобретени  Стекло, включающее SiO2, , АЬОз, ZnO, NasO, отличающеес  тем, что, с целью повышени  пропускани  рентгеновских лучей, оно содержит указанные компоненты в следующих количествах, вес. о/о: SiOa69-75 ВгОз12-18 АЬОз2,5-3,0 ZnOДО 2,5 Na2O4-6The invention relates to high transmission X-ray glasses. Glass grade C47-1 (46) for the manufacture of glass balloons of X-ray devices containing SiO2, BrO3, ABO3, ZnO, NaaO is known. The proposed glass makes it possible to increase the transmission of X-rays to the glass balloon and its electrical strength. This is achieved by using glass: The linear expansion coefficient a-10 1 / ° C 48.5 Softening temperature, ° C Heat resistance, ° C The temperature at which the specific volume resistance of the glass is 100 mOm (Tc-100) is not less 220 5 10 15 20 25 losses, tg6 -10 at a frequency of 10 Hz42 Electrical strength, kV / mm260 Chemical resistance,% loss 0.06 {I hydrolytic class) Transmission of X-rays by glass cylinders with a wall thickness of 2.0 mm and 1.6 mm, made of the described glass, increased by 1.5 times in comparison with cylinders with t th same wall thickness but made of S47-1 brand glass. Glass is technologically advanced and can be brewed in batch baths. The subject of the invention is Glass, including SiO2, AO3, ZnO, NasO, characterized in that, in order to increase the transmission of X-rays, it contains these components in the following amounts, wt. o / o: SiOa69-75 ВгОз12-18 АЛОз2,5-3,0 ZnODO 2,5 Na2O4-6
