Study on Elimination of Oxygen Absorption in Chalcogenide Glass

Decreasing the absorption is a key process for chalcogenide glass preparation. The glass character of oxygen absorption and some means to remove the oxygen absorption were introduced.

含锗硫系玻璃中氧吸收的消除

降低材料的吸收是硫系玻璃研制的关键之一。本文指出了硫系玻璃中氧吸收的本质，介绍了消除氧吸收的三种方法，分别为真空焙烧高纯原料，在氢气氛中加热石英反应器及在原料中填加微量铝。
