Scope

This part of EN 725 describes a method for the determination of impurities in barium oil tanate powders using inductively coupled plasma and atomic emission (ICP-AES). The procedure can only be applied to stochometric barium ttanate. The maximum measurable concentrations for each individual impurity are as follows: 　——Sr: 4000 ppm - Ca: 500 ppm - K: 200 ppm - Na, Mg, Al, Fe, Nb: 1000 ppm The minimum concentrations or detection limits are in the range of 1 ppm to 5 ppm.
