Abstract:
Objective:To analyze the characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng via X-ray diffraction. Methods:The fingerprint and common peaks of gypsum fibrosum from different areas were analyzed via X-ray diffrac-tion, and the characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng were identified Results:The finger-prints of X-ray diffraction of gypsum fibrosum from different areas were obtalned. Sixteen common peaks were determined, and two characteristic peaks of gypsum fibrosum from authentic product area Yingcheng were determined via X-ray diffraction with interplanar spacing of 1. 68 and 1. 51, respectively. Conclusion:The determination of two characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng can distinguish gypsum fibrosum from the other areas and provide basis for the quality evaluation of gyp-sum fibrosum.
