A method for the estimation of Na₂O and K₂O 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.

ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometry), CIROS^CCD, CRM (Certified Reference Materials), Double distilled water, alkali (Na₂O and K₂O), BCS(British Certified Standard).
