摘    要:描述了碳硅石压腔的结构和特点。碳硅石压腔主要包括碳硅石压砧、支撑加压系统、加热系统和金属垫片等部分。合成碳硅石的硬度高、热导性好、膨胀系数小、热稳定性好,并且它的晶体颗粒大,透明度好,价格也很便宜,因此是一种很好的压砧材料。还介绍了应用碳硅石压腔对Na2CO3溶液、Na2SO4溶液、水的拉曼光谱进行高温高压原位测量的实例。

关 键 词:高温高压  碳硅石压腔  拉曼光谱  原位测量

Abstract:This paper introduces the structure and the feature of moissanite anvil cell, w hich is composed of moissanite anvil, supporting and creating pressure syste m, h eater system and metal gasket. Because of its high hardness, high heat conducta nce, low thermal expansion, good thermal stability and low price, moissanite is a good material of anvil for high-temperature and high-pressure experimental s tudies. With this cell, the Raman spectrum of sodium carbonate solution, sodium sulfate solution and distilled water has been in situ measured under high- temperature and high-pressure. With increasing pressure, it can be observed th at the 1 066 cm -1 Raman modes of sodium carbonate solution and the 982 cm -1 Raman modes of sodium sulfate solution shift to high wave numbers obv iously. With increasing temperature, the frequency at maximum intensity shift s to high wave numbers, the full width at half-maximum intensity decreases in the Raman spectrum of water.
Keywords:High-temperature and high-pressure  Moissanite anvil cell  Raman spectrum  I n-situ measurement
