| 摘 要： | 锰方硼石是一种罕见的锰氯硼酸盐矿物(Mn_3B_7O_(13)Cl),天津蓟县锰方硼石矿床是世界上唯一一个锰方硼石矿床,该地锰方硼石矿物粒度细小(50~300 nm),与美国锰方硼石存在明显差别。目前涉及我国锰方硼石的研究较少,为了探究稀有矿物蓟县锰方硼石矿物学和材料学特征,本文对其进行振动光谱和高温拉曼光谱研究。常温振动光谱结果表明,蓟县锰方硼石与美国锰方硼石各主要谱带归属一致,但峰位整体上表现为向高频方向偏移且谱峰宽、强度小。高温拉曼光谱显示,随着温度升高,谱带向低频方向偏移,位移距离随温度升高呈现先增大后减小的趋势,且在680~687K处位移距离出现转折。蓟县锰方硼石粒度细小是造成上述谱峰变化的主要原因。本文运用高温拉曼技术对粒度极为细小的锰方硼石进行测试分析,研究其谱峰变化与相变的关系,实验证明高温拉曼光谱可以作为研究矿物相变的一种有效手段。

| Abstract: | Chambersite (Mn3B7O13Cl) is a type of rare mineral. The Chambersite deposit in Jixian, Tianjin is the only commercially valuable deposit in the world. The Chambersite particle in Jixian is very fine (50-300 nm), which is different from that of American Chambersite. Until now, little study was carried out has been conducted on Chinese Chambersite. In order to explore the mineralogical and material characteristics of Chambersite in Jixian, a Vibration Spectrum and high-temperature Raman Spectrum were recorded. Normal-temperature Vibration Spectrum shows that the main spectrum band assignment of Chinese Chambersite is the same as that of American Chambersite. However, as a whole, the peak position is shifted toward the high-frequency direction and the spectral width and intensity are small. High-temperature Raman Spectroscopy shows that with the increase of temperature, bands generally shift to the low frequency, the displacement distance increases first and then decreases, and the displacement distance turns at 680-687 K. The small particle size is the main reason for spectrum peak changes. High-temperature Raman Spectroscopy technique was used to test and analyze Chambersite with very fine particle size, and the relationship between the peak change and phase transition was studied, thus demonstrating that high temperature Raman Spectroscopy can be used as an effective method to study mineral phase transition. |
