Изобретение относитс  к фотохромным стеклам, которые найдут применение при производстве солнечных очков, застеклении в автомобил х и здани х.The invention relates to photochromic glasses, which will find use in the manufacture of sunglasses, glazing in automobiles and buildings.

Известно фотохромное стекло, содержащее , вес. %:Known photochromic glass containing, in weight. %:

SiOa 76-82; LigO 8-14; ВгОз 0,2-3,8; АЬОз 1-4,8; Ag 0,2-0,7; СиО 0,01-0,08; F 1-3; С 0,5-2,8; Вг 0,3-1,5; 3-10. Стекло дополнительно может содержать, вес. %: МпО 0,001 - 1; BiaOs 0,3-3; ZnO 0,01 - 1; PbO 0,01-0,3; 0,3-3; РегОз 0,001-0,1; EuzOg 0,001-0,1, CaO 1-5;MgO 1-5 1.SiOa 76-82; LigO 8-14; VgOz 0.2-3.8; ABOZ 1-4,8; Ag 0.2-0.7; CuO 0.01-0.08; F 1-3; C 0.5-2.8; Вг 0,3-1,5; 3-10. Glass may additionally contain weight. %: MpO 0.001-1; BiaOs 0.3-3; ZnO 0.01-1; PbO 0.01-0.3; 0.3-3; RegOz 0.001-0.1; EuzOg 0.001-0.1, CaO 1-5; MgO 1-5 1.

Стекло вар т в слабоокислительной среде при 1300-1500° С.Glass is cooked in a weakly oxidizing environment at 1300–1500 ° C

Фотохромпые свойства стекло приобретает в процессе отжига при 400-500° С в течение 1-2 ч или в процессе повторной термообработки.The glass acquires its photochromic properties in the process of annealing at 400–500 ° C for 1–2 h or in the process of repeated heat treatment.

Стекло обладает высокой скоростью потемнени , обесцвечивание происходит в темноте в течение нескольких часов.The glass has a high rate of darkening, discoloration occurs in the dark for several hours.

Цель изобретени  - увеличение скорости потемнени  и просветлени .The purpose of the invention is to increase the rate of darkening and enlightenment.

Это достигаетс  тем, что стекло содержит , вес. %:This is achieved in that the glass contains weight. %:
