[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.


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.
