Chemical analysis of ferrous materials - Analysis of ferro-silicon - Determination of Al, Ti and P by inductively coupled plasma optical emission spectrometry
This Technical Report describes an inductively coupled plasma optical emission spectrometric method for the determination of Al, Ti and P contents in Ferro Silicon materials. The method is applicable to: - Al content between 0,2 and 2 %;- Ti content between 0,02 and 0,25 %;- P content between 0,005 and 0,05 %.This Technical Report also describes the general requirements for analysis by inductively coupled plasma optical emission spectrometry, the preparation and dissolution of the test sample and the method of calculation of the results.The procedure is valid for the analytical lines given in Table 1. This table also gives, for each line, the spectral inter
