In order to determine alloying elements in ferromanganese and ferrochromium, the application of calibration curve method and of calculation method by Hirokawa's equation was examined. Samples for X-ray irradiation were powder samples and solution samples. Powder samples were prepared by mixing the acid solution of samples with the graphite powder, which was evaporated to dryness. However, the solution samples were prepared by dissolving ferromanganese with nitric acid and by fusing ferrochromium with sodium peroxide. Using these samples, manganese in ferromanganese or chromium in ferrochromium was determined within the standard deviation of about 3.5 per cent.
