scope:
This part of EN 725 describes a method for the determination of impurities in barium titanate powders using inductively coupled plasma optical emission spectroscopy (ICP-OES). The method is applicable only to stoichiometric barium titanate. The maximum concentrations measured for each impurity are as follows: Sr 4 mg/g (4 000 ppm) Ca 500 ug/g (500 ppm) K 200 ug/g (200 ppm) Na, Mg, Al, Fe, Nb 100 µg/g (100 ppm) The minimum concentration or detection limits are from 1 ug/g to 5 ug/g (1 ppm to 5 ppm).
