| Abstract
|
| [Objective] To investigate the X-ray diffraction spectrum of processed product of gypsum (calcined gypsum)and, establish the X-ray diffraction finger print and estimate the application value of this method to distinguish gypsum, calcined gypsum and chemical reagents. [Methods] The calcined gypsum was qualitatively analyzed by adopting X-ray diffraction and the semblance degree of the pub-lic peaks, including angle cosine and correlation coefficient as the research parameters. They were compared by using Origin 6.0 soft-ware. [Results] The semblance of calcined gypsum X-ray diffraction finger print public peaks was exceeded 95%. It could distinguish gypsum and chemical reagents obviously. [Conclusion] The method of X-ray diffraction analysis of calcined gypsum has good specificity and is accurate and feasible and can be used to distinguish gypsum and chemical reagents and can reflect the calcined gypsum internal quality feature. |
