| 摘 要： | 利用ALINKAM（TMS94）温度控制系统产生高温,在31℃～301℃温度范围内,对石膏（CaSO4.2H2O）晶体进行了原位高温拉曼光谱法研究。结果表明,在151℃附近,对称性伸缩振动范围属于熟石膏的特征拉曼振动模式（1026cm-1出现）,表明石膏转变成熟石膏（也叫烧石膏）,继续加温至301℃,熟石膏（CaSO4.0.5H2O）的拉曼光谱没有明显变化,熟石膏晶体结构稳定。 |

| Abstract: | In-situ Raman spectra of gypsum have been studied in the temperature range of 31～301℃ at ambient pressure. The high temperature was obtained with a Linkam (TMS 94) temperature control system. Near the temperature of 151℃ , a new Raman peak at 1026 cm~(-1) was observed in the range of symmetric stretching vibration. It is the characteristic vibration mode of bassanite, indicating that gypsum has transformed into bassanite. There is no obvious spectral change in the temperature range of 151～301℃ , showing that the crystal structure of bassanite is stable. |
