[Determination of Fe, Al, Ca, Ti, P and Cu in silicon metal by XRF].
This article puts forward a sample preparation method that first dissolve the sample by acid and evaporate the solution then melt the remains by flux. This method resolves the problem that silicon metal can't easy to prepare sample by fusion, and it can determine several elements in the sample simultaneously. This method overcomes the limit of standard sample and removes the matrix effects. The range of determination is wide and the results is accurate. The condition of preparing sample was confirmed by test.
