ThCl4-PbCl2系统熔盐和玻璃的拉曼光谱及结构
RAMAN SPECTRA AND STRUCTURE OF ThCI4-PbCI2 SALTS AND GLASSES
【摘要】 <正> 迸年来,完全由氯化物形成的玻璃正引起人们的广泛关注。为描述这类玻璃的结构,已经提出了无序阴离子堆积模型,但这方面的实验研究尚未见报道。本文由ThCl4-PbCl2系统急冷熔盐和40ThCl4·30PbCl2·30NaCl(TPN)、40ThCl4·30KCl·30NaCl(TKN)玻璃的拉曼光谱讨论了以ThCl4和PbCl2为基础组分的氯化物玻璃结构。 用Spex-Ramalog谱仪以背散射方式测试了密封在石英管内的ThCl4-PbCl2粉末状急冷熔盐和块状玻璃样品的拉曼光谱。激发光为Ar+离子激光的5145(?)线。样品制备另见报
【Abstract】 The Raman spectra of ThCl4-PbCl2 salt system, 40ThCl4·30KCl·30NaCl and 40ThCl4·30PbCl2·30NaCl glasses have been investigated. The Raman peaks of the glasses at 280 cm-1 are attributed to the increase of coordination number of Th4+ by introducing alkali ions, and the peak at 200cm-1 is attributed to the breaking of [PbCl3]n long chain. The units of Pb2+ and Th4+ are considered existing separately.
