摘　　要：考察了国内不同产地纯滑石粉的X射线衍射图谱,并与JADE谱图分析软件中所提供的滑石的JCPDS卡中标准数据比对,结果表明,国内不同产地滑石粉具有相同的XRD指纹特征。考察了滑石粉快速定性筛选的可靠性和精密度,以滑石三强线的面间距d值作为定性指标,以衍射峰相对强度(I/I1)作为半定量指标,建立了滑石相含量大于70%的滑石粉的X射线衍射快速定性筛选判定方法,为出口滑石粉的检验监管提供快速准确的技术支持。The X-ray diffraction （XRD） spectra of pure talcum powder from different production areas in China were investigated and compared with the standard data of talcum powder in JCPDS card pro- vided in JADE spectral analysis software. The results showed that, the talcum powder from different production areas showed the same XRD fingerprint characteristics. The reliability and precision of rapid and qualitative screening method of talcum powder were investigated. The rapid qualitative screening method of talcum powder （the content of talcum phase was higher than 70%） was estab- lished with interplanar distance （d） of three lines as qualitative index and relative intensity of diffrac- tion peak （ I/I1 ） as semi-quantitative index. This method provided rapid and accurate technical sup- port for the inspection and supervision of exported talcum powder.
