Zn coordination state in Na2O-ZnO-B2O3 glasses were measured with a common single crystal X-ray fluorescence spectrometer. The result shows.1. A common single crystal X-ray fluorescence spectrometer can be used to determine coordination of Zn in glasses.2. The Zn2+ chemical shift data of 6-fold is negative, while that of 4-fold is positive.3. All the Zn2+ in Na2O-ZnO-B2O3 glasses system is 4-fold, the results are in agreement with the results of EXAFS.
