石膏的X射线衍射鉴定研究

目的:建立石膏与煅石膏、滑石粉、石膏掺滑石粉新的鉴定分析方法。方法:应用X-射线衍射分析方法,对石膏、煅石膏、滑石粉和石膏掺滑石粉进行X-射线衍射指纹图谱分析及特征标记峰鉴别。结果:通过对四种样品进行分析鉴定,获得了石膏、煅石膏、滑石粉及石膏掺滑石粉的X-射线衍射图谱及特征标记峰值。结论:实验结果表明,X-射线衍射图谱鉴定法可用于石膏与煅石膏、滑石粉及石膏掺滑石粉的鉴定。

Studies on Identification of Gypsum Fibrosum by X-ray

Objective:To establish a new identification and analysis method of gypsum fibrosum,gypsum fibrosum praeparatum,pulvis talci and gypsum fibrosum blended with pulvis talci.Methods:Powder X-ray diffraction fingerprint spectra method.Results:Experiments and analysis were carried out on four samples.The standard X-ray diffraction fingerprint spectra and characteristic diffraction peaks of each sample were obtained.Conclusion:The experimental result indicates that X-ray diffraction fingerprint spectra can be used to identify and analyze gypsum fibrosum,gypsum fibrosum praeparatum,pulvis talci and gypsum fibrosum blended with pulvis talci.
