(Sb_2O_3)_(1-x)(Sb_2S_3)_x系新型氧硫混合红外玻璃的研究

Study of New Oxysulphied Glasses from (Sb2O3)1- x (Sb2S3) x System

首次制备了一类新型的含（Ｓｂ２Ｏ３）１－ｘ（Ｓｂ２Ｓ３）ｘ的氧硫混合体系玻璃，测定了玻璃的组成、形成区域，并用ＤＴＡ、ＩＲ、ＵＶ光谱对其性能进行了研究，同时与Ｓｂ２Ｏ３单组份玻璃，Ｓｂ２Ｏ３－ＲＸ２（Ｒ＝二价金属离子）系玻璃进行了比较。该玻璃易于制备，化学稳定性好，透光区０．７～７．０μｍ，Ｔｃ－Ｔｇ＞９０℃，通过远红外光谱的分析，对玻璃的结构进行了初步研究。

New oxysulphied glasses involving Sb2O3 and Sb2S3 have been prepared.Glass forming regions have been shown.The thermal and optical properties of the glasses have been measured and compared with the glass of Sb2O3 and the glasses of Sb2O3-RX2.They are easy to prepare,chemically stable and their transparent band is from 0.7m up to 7.0m. Tc - T g>90.A structure model is proposed on the base of Far-IR spectra.
