THE INFLUENCE OF HEAT TREATMENT ON OPTICAL PROPERTY OF ION EXCHANGE PHOTOCHROMIC GLASS

摘要

In this paper, the influence of heat treatmenton transmittance and the photochromic of ion exchange pho-tochromic glass was studied, the microstructure of glass aswell as the forming of AgX crystals were discussed. It is be-lieved that heat treatment temperature affects precipitating ofAgX crystal .and the AgX crystal is a dominant factor af-fecting surface photochromic properties of ion exchange pho-tochromic glass.
