title: [Studies on identification of gypsum fibrosum by X-ray].
abstract: 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.
  
  
  CONCLUSIONS
  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.
