掺钕磷酸盐激光玻璃除铂工艺研究

Research on the Removing Platinum Impurities Processing in Nd^(3+)-doped Phosphate Laser Glass

铂微粒对磷酸盐激光玻璃的性能有巨大的影响,本文探索了铂微粒形成和进入玻璃的机制,研究了熔制温度、时间和氧分压等不同工艺参数对铂微粒含量的影响。研究表明强氧化气氛、高的熔炼温度可以显著消除磷酸盐激光玻璃中的铂微粒。

Platinum Impurities had a significant effect on the performance of phosphate laser glasses.The mechanism on the formation and dissolution of platinum impurities were investigated,and the effects of various smelting temperature,smelting time and partial pressure of oxygen on the concentration of the platinum impurities were studied.The experimental results showed that oxidizing atmosphere,high smelting temperature had a good effect on removing platinum impurities in phosphate laser glass.
