摘要
本文介绍了TiF_6光学玻璃的制作。研究了这种玻璃内的K^+或Na^+离子与Ag^+离子交换。使用双光束干涉法观测了干涉纹、并用电子探针扫描电镜测量了Ag^+、K^+和Na^+离子的浓度分布,还着重研究了离子交换后的玻璃裂纹和着色问题。最后,对结果作了讨论。
This paper introduces manufacture of TiF6 optical glass and studies exchange of K+ or Na+ in the glass for Ag+ ions. The interference stripes are observed by double- beam interferometer and the concentration distributions of Ag+, K+ and Na+ ions in the glass is measured by electronic probe scanning microscope The article also gives emphasis to the study of cracking and colouring probtems of the glass after ion exchanging and discusses the results abtained.
