Aluminium fluoride for industrial use. Determination of trace elements. Wavelength dispersive X-ray fluorescence spectrometric method using pressed powder tablets1 Scope This International Standard describes an X ray fluorescence spectrometric (XRF) method for the determination of aluminium fluoride (AlF3) from the content of fluorine and the content of trace elements in the test specimen. The method does not determine the oxygen content. The calibration reference materials are not specified in this method. The method is applicable to industrial grade aluminium fluoride where the concentration range for
