磷酸盐激光玻璃中铂颗粒密度与氧化还原平衡关系的研究

Investigation on Relationship between Platinum Inclusion Density and Platinum Redox Equilibrium in Phosphate Laser Glass

用吸收光谱法研究了Ｒ２Ｏ—ＢａＯ—Ｐ２Ｏ５系统磷酸盐激光玻璃中铂颗粒密度与铭的氧化还原平衡的关系。结果表明，玻璃中铂颗粒密度随平衡向右移动而减小；玻璃中平衡随熔炼气氛中氧分压增大、熔炼温度升高而向右移动，当足够大时，铂颗粒不能形成。

With absorptance spectra of platinum ions; relationship between platinuminclusion density and platinum redox equilibrium in R2O-BaO-P2O5 system phosphate laserglass was investigated. The results show that platinum inclusion density reduces as theequilibrium shifts towards right.With the melting temperature or OZ perilalpressure of melting atmosphere increased;the equilibrium shifts towardsright.When is large enough; platinum inclusions can not be formed.
