【Abstract】 The correlativity between photochromic properties and influencing factors of photochromic glass containing silver halide was studied by correlation factor analysis method. The analysis results show that the correlation factors manifest appropriately the correlativity between photochromic properties and influencing factors. The results also indicate that increasing the contents of SiO 2, Al 2O 3 in the basic components contribute to modification of the photochromic properties, whereas the effect of B 2O 3 is just opposite. And the increase of contents of alkali and alka_line earth metal oxides leads to the degradation of photochromic properties. In a word, increasing structure factor Ψ will degrade the photochromic properties. For the effect of photosensitive agents, Au + and Br - can improve the photochromic properties very greatly, but the effect of Ag +, Cu 2+ and Cl - is comparatively small. The effect of heat treatment is rather great,increasing the temperature of heat treatment makes fading coefficient increase remarkably, however, darkening degree decreases with the increase of heat treatment temperature.更多还原
