ObJective: To establish the analysis method for gypsum and calcined gypsum by XRPD. Method: XRPD fingerprints and strong lines of gypsum and calcined gypsum were analyzed. Result: Sixteen specimens of gypsum
5 specimens of calcined gypsum and gypsum contained preparation Qingyanliuweisan were analyzed and identified by XRPD. XRD strong lines of gypsum and calcined gypsum were acquired. Conclusion: The method established can be used for identification of gypsum and calcined gypsum because of different XRPD fingerprints.
