title: [Determination of Fe, Al, Ca in silicon metal by XRF spectrometry].
abstract: Fe, Al, Ca in silicon metal were measured by XRF using powder pressed method to prepare the sample. The conditions of preparing the sample disc were discussed, and the strength of the sample disc, was solidified through the binder added. Interelement absorption and enhancement effects are corrected by using the experience coefficient method. The precision and accuracy of the XRF method are excellent as compared with classical chemical method.
