| Abstract: | Pressed powder pellets of graphite electrode powder were used to determine the content of sulphur instead of wet chemical analysis by XRF.Calibration curve was prepared by Chinese coke standards mixed with starch.The size of sample and the press of pellets were also tested so as to find the best analysis conditions.The scattering background intensity was used as a reference to correct the matrix effect.The precision and accuracy of the results meet the requirement for the powder quality analysis. |
