摘要
首次报道了 CdCl_2-PbCl_2-KCl 系统的玻璃形成区,以及若干以 CdCl_2和 PbCl_2为基的多元组成玻璃的形成。IR 光谱表明,这些玻璃的透红外范围可达18μm 以上,为 CO_2激光的传输提供了可能的材料。PbCl_2的引入使玻璃的化学稳定性得到显著的改善,并使玻璃的透红外范围略有扩展。DSC 研究表明,PbCl_2使玻璃的转变温度降低,并有导致玻璃分相的作用。
The glass formation region in the ternary system of CdCl_2 -PbCl_2-KClwas identified for the first time in this work,and the formation of some multicomponentglasses based on CdCl_2 and PbCl_2 was also reported.The IR transmitting spectra studiesshow that the IR transparent region of these glasses is up tp 18μm,and this is excellent forthe transmisson of CO_2 laser.The chemical durability of CdCl_2 based chloride glass isimproved by the introduction of PbCl_2.It is suggested by DSC studies that the glass transi-tion temperature of CdCl_2 based glass decreases,and phase seperation occrurs in someglasses due to the introduction of PbCl_2.
