In the calibration curve method of the quantitative analysis with EPMA, a calibration curve is generally made by plotting the measured relative X-ray intensity K to the weight fraction of composition C. Ziebold and Ogilvie found empirically that a plot of C/K against C is approximate linear in the binary alloy system and its straight line function is written [numerical formula]. Then, some experiments to determine wheather this function is also applicable in the case of sulfide system have been carried out. It was shown that a plot of C/K against C makes also simple straight line in the experiments on the three binary systems of Bi_2S_3-Sb_2S_3,PbS-Sb_2S_3,and Cu_2S-Bi_2S_3. The fact suggests the possibility that the method using empirical correction factor developed by Bence and Albee on silicate is useful on sulfide as well.
