scope:
This part of EN 725 describes a method for the determination of impurities in barium titanate powders, using inductively coupled plasma atomic emission (ICP-AES). The method is applicable only to stoichiometric barium titanate. The maximum concentations measured for each impurity are as follows: - Sr: 4000 ppm -Ca: 500 ppm - K: 200 ppm - Na, Mg, Al, Fe, Nb: 100 ppm. The minimum concentration or detection limits are from 1 ppm to 5 ppm.
