(54) ФОТОХРОМНОЕ СТЕКЛО(54) PHOTOCHROME GLASS

1one

Изобретение отноштс  к составам стекол, используемых дл  изготовлени  очковых линз, световых фильтров, в приборах дл  записи информации.The invention relates to compositions of glasses used for the manufacture of spectacle lenses, light filters, in devices for recording information.

Известно фотохромное стекло на основе Pj Os, Si02, , 1. Однако стекло данного состава не обладает способностью растворить большие количества серебра, так как содержит, компонент SiOa, имеет низкую степень потемнени . Использование SiOa требует более длительного режима варки.Photochromic glass is known on the basis of Pj Os, SiO2, 1. However, glass of this composition does not have the ability to dissolve large amounts of silver, because it contains a component of SiOa and has a low degree of darkening. Using SiOa requires a longer cooking mode.

Наиболее близким к изобретению  вл етс  фото: фомное стекло на основе PyOs и 6263 РЬ Указанное стекло содержит РзО; в сравнительно малых количествах, что не позвол ет получать стекла с высокой степенью потемнени .The closest to the invention is a photo: phome glass based on PyOs and 6263 Pb. The specified glass contains PZO; in relatively small quantities, which does not allow to obtain glasses with a high degree of darkening.

Целью изобретени   вл етс  повьппение чувствительности стекла в коротковолновой части шектра.The aim of the invention is to increase the sensitivity of glass in the shortwave part of the spectrum.

Достигаетс  эта цель тем, что стекло, включающее PjOs, KjO, AljOg, BaO, АдгО, CujO, Cl, Br, содержит указанные компоненты в следующих количествах (в вес.%):This goal is achieved by the fact that glass, including PjOs, KjO, AljOg, BaO, AdO, CujO, Cl, Br, contains these components in the following amounts (in wt.%):

Описьшаемое стекло обладает чувствительностью в коротковолновой части спектра и высокой степенью потемнени .The inscribed glass has a sensitivity in the shortwave part of the spectrum and a high degree of darkening.

Конкретные составы стекол приведены в табл. 1.Specific compositions of the glasses are given in table. one.

Стекла вар т из обьмных шихтных материалов при 1100-1200° С, Дл  придани  фото фомных свойств они подвергаютс  специальной наводке в течение 1-3 час при температуре 400-450° С,The glasses are made of obshmnyh charge materials at 1100-1200 ° C. In order to impart photo properties, they are subjected to special guidance for 1-3 hours at a temperature of 400-450 ° C,

Фотохромные характеристики указанных стекол приведены в табл. 2.Photochromic characteristics of these glasses are given in table. 2

Как видно из таблицы, стекла обладают высокой степенью потемнени , а нулевое значение критери  релаксации позвол ет использовать его дл  }фанвни  информации.As can be seen from the table, the glasses have a high degree of darkening, and the zero value of the relaxation criterion allows using it for fanning information.
