Abstract

In a refractory manufacturing industry with widely diversified products from silica (SiO2 ≥ 90%) to high alumina materials (Al2O3 ≥ 90%) and basic refractory from periclase (MgO ≥ 95%) to chrome-periclase (Cr2O3 ≤ 40%) mixtures, introduction of a single method of analysis is impractical both economically and precision-wise. Three different methods are proposed with a view to realistic needs: (a) Direct ratio method, (b) calibration curve ratio method, and (c) matrix normalization by fusing with Li2B4O7 and La2O3 into a glass bead followed by grinding and pelletizing. Statistical regression equations were used for the calibration curves from available NBS standards 15-20 samples previously analysed by wet chemical methods by ratioing with relevant reference samples. In most cases, the relative standard deviation was 2 - 8%.
