X‐ray fluorescence analysis under high vacuum (∼10 −6 torr) was applied to the determination of fluorine in slags. Slag samples are converted into glass beads using a fusion method and the fluorescent X‐ray intensity of characteristic X‐ray F Kα (1.83 nm) is measured to determine fluorine. The calibration curve has excellent linearity and accuracy; σ d is 0.18% for 11 kinds of samples involving fluorine of 0.10% to 16.78% (mean: 6.96%).
