硫化锰微晶简易可控合成与表征

Simply Controllable Synthesis and Characterization of MnS Micro-sized Crystals

以氯化锰(MnCl 2·4H 2O)和硫化钠(Na 2S·9H 2O)为原料,采用水热法在不同的反应温度下成功得到了硫化锰微晶。产物经X射线衍射仪、场发射扫描电子显微镜、傅里叶红外光谱仪和激光共聚焦显微拉曼光谱仪测试表征后表明,水热反应温度对MnS的晶型影响很大,随着水热反应温度的升高,产物将从γ-MnS向α-MnS转变。200℃条件下通过水热法合成了形貌均一的八面体α-MnS。

MnS micro-sized crystals were successfully synthesized using MnCl2·4 H2O and Na2S·9 H2O as raw materials by a hydrothermal method. The crystal structure, morphology and compositions of as-synthesized products were characterized by X-ray diffraction, Field Emission Scanning Electron Microscope, Fourier Transform Infrared Spectrometer and Laser Confocal Micro Raman Spectrometer. Results showed that the reaction temperature play a vital role in controlling the crystal structure of MnS. With the increase of the reaction temperature, the γ-MnS would be transformed to α-MnS.Cure octahedron phase of α-MnS would be obtained at 200℃.
