Description
Изобретение относится к производству оптического стекла, устойчивого к действию гамма-излучения, более конкретно к стеклам с высоким показателем преломления, обладающим повышенным светопропусканием в УФ- и видимой областях спектра. The invention relates to the production of optical glass that is resistant to gamma radiation, and more particularly to glasses with a high refractive index, with increased light transmission in the UV and visible regions of the spectrum.
Известно оптическое стекло (пат. ГДР N 242801, кл. С 03 С 3/068, 1987) следующего состава, мас. SiO2 3,1-7,9; B2O3 27,5-30,8; La2О3 37-44; Y2O3 1,8-8,3; ZnO 4,5-7,5; ZrO2 5,5-8,8; Al2O3 1,3-3,4; SrO 1,3-3,2; WO3 0,6-2,0; TiO2 0-0,4. Стекло обладает показателем преломления nd1,741-1,744, однако недостаточно гамма-устойчиво.Known optical glass (US Pat. GDR N 242801, class C 03
Наиболее близким по составу ингредиентов, технической сущности и достигаемому эффекту к заявляемому стеклу является стекло (СТК-119 по ОСТ 3-4931-81, 1981 г) со следующим содержанием компонентов, мас. Y2O3 5,90; ZnO 12,28; B2O3 32,02; La2O3 36,41; СeO2 0,3; SiO2 3,90; CaO 1,94; Ta2O5 2,9; ZrO2 4,35. Недостатком стекла-прототипа является низкая категория по показателю ослабления (преимущественно 7-я) и малое светопропускание.The closest in composition of ingredients, technical essence and the achieved effect to the claimed glass is glass (STK-119 according to OST 3-4931-81, 1981) with the following content of components, wt. Y 2 O 3 5.90; ZnO 12.28; B 2 O 3 32.02; La 2 O 3 36.41; CeO 2 0.3; SiO 2 3.90; CaO 1.94; Ta 2 O 5 2.9; ZrO 2 4.35. The disadvantage of the prototype glass is the low category in terms of attenuation (mainly 7th) and low light transmission.
Изобретение обеспечивает повышение светопропускания в ультрафиолетовой и видимой областях спектра и категории по показателю ослабления при сохранении гамма-устойчивости (ΔD ≅ 0,030). The invention provides an increase in light transmission in the ultraviolet and visible regions of the spectrum and category in terms of attenuation while maintaining gamma stability (ΔD ≅ 0.030).
Сущность изобретения заключается в том, что оптическое стекло, устойчивое к действию гамма-излучения, включает Y2O3, ZnO, B2O3, La2O3, CeO2, CaO, SiO2, Ta2O5, ZrO2; причем в отличие от прототипа оно дополнительно содержит Sb2O3 и SnCl2 при следующем соотношении компонентов, мас. Y2O3 5,0-6,0 ZnO 10,0-13,0 B2O3 30,0-33 La2O3 34,0-38,0 CeO2 0,2-0,5 SiO2 2-5 CaO 1-3 Ta2O5 1-4 ZrO2 2,5-5 Sb2O3 0,35-0,5 SnCl2 0,7-1,0 при этом содержание компонентов SnCl2 и Sb2O3 в составе стекла удовлетворяет соотношению SnCl2/Sb2O3 1,7-2,0.The essence of the invention lies in the fact that the optical glass, resistant to gamma radiation, includes Y 2 O 3 , ZnO, B 2 O 3 , La 2 O 3 , CeO 2 , CaO, SiO 2 , Ta 2 O 5 , ZrO 2 ; moreover, in contrast to the prototype, it additionally contains Sb 2 O 3 and SnCl 2 in the following ratio of components, wt. Y 2 O 3 5.0-6.0 ZnO 10.0-13.0 B 2 O 3 30.0-33 La 2 O 3 34.0-38.0 CeO 2 0.2-0.5 SiO 2 2-5 CaO 1-3 Ta 2 O 5 1-4 ZrO 2 2.5-5 Sb 2 O 3 0.35-0.5 SnCl 2 0.7-1.0 while the content of the components SnCl 2 and Sb 2 O 3 in the composition of the glass satisfies the ratio SnCl 2 / Sb 2 O 3 1,7-2,0.
В рассматриваемой системе при введении SnCl2 при указанных соотношениях остальных компонентов и отношении SnCl2/Sb2O3 создаются окислительно-восстановительные условия, переводящие церий в основном в трехвалентное состояние, в результате чего существенно повышается пропускание в ультрафиолетовой и видимой областях спектра, повышается категория по показателю ослабления при сохранении гамма-устойчивости, т.е. достигается необходимый технический результат.In the system under consideration, with the introduction of SnCl 2 at the indicated ratios of the remaining components and the SnCl 2 / Sb 2 O 3 ratio, redox conditions are created that transfer cerium mainly to the trivalent state, as a result of which the transmission in the ultraviolet and visible regions of the spectrum increases significantly, and the category increases in terms of attenuation while maintaining gamma stability, i.e. the necessary technical result is achieved.
Изобретение поясняется таблицей, где приведены составы стекол и их свойства. The invention is illustrated in the table, which shows the compositions of glasses and their properties.
Варку стекол на основе оксидов, карбонатов, нитратов проводили в лабораторных и производственных условиях в платиновых тиглях 2 л и 60 л соответственно. Температура варки 1310оС. Отжиг при температуре 630о С. Как видно из таблицы, предлагаемое стекло имеет параметры, превышающие ранее достигнутые и зафиксированные, например, по сравнению с серийным стеклом СТК 119 (ОСТ 3-4931-81). Оно характеризуется повышенным светопропусканием, 3-й категорией по показателю ослабления (μA) и смещением края поглощения в ультрафиолетовую область спектра на 60 нм при сохранении гамма-устойчивости.Glasses based on oxides, carbonates, nitrates were melted in laboratory and industrial conditions in platinum crucibles of 2 l and 60 l, respectively. The cooking temperature of 1310 C. Annealing at a temperature of 630 C. As seen from the table, the glass has proposed parameters exceeding previously achieved and documented, for example, compared with the serial glass STK 119 (OST 3-4931-81). It is characterized by increased light transmission,
