Abstract
A method for the estimation of Na 2 O and K 2 O in the feed materials of sinter plants and blast furnaces, intermediate products like sinter, slag generated in steel plants, using Inductively Coupled Plasma Emission spectrometer is developed. Superiority of this method compared to the conventional techniques with respect to accuracy and repeatability is illustrated. Validation of this method is ascertained by carrying out tests with certified reference materials.
