Abstract

The photochromatic glass consists of oxide SiO2, B2O3 and Al2O3 and photochromatic material Ag, CuO, Cl and Br, as well as 3-6 kinds of characterized alkali oxide. Its preparation process includes melting with the standard material mixture inside platinum crucibles at 1420-1480 deg.c, clarifying, stirring at 1150 deg.c, mechanically pressing into lens blank, and finally reheating at 600 deg.c for about 40 min. The photochromatic glass has fast photochromatic rate, ultraviolet resistance and high refractivity.
