MULTIELEMENTAL ANALYSIS OF METALLURGICAL SAMPLES BY THERMAL-NEUTRON ACTIVATION

Instrumental neutron activation analysis (INAA) was applied to investi gate a total of 16 samples of raw materials, intermediate and final pr oducts involved in metallurgical processes in Romanian Iron and Steel Works Sidex Galatzy: iron ores and pellets from different regions of t he world, cast iron, slag and steels. A series of chemical elements wa s determined in the analyzed samples: Al, As, Ce, Co, Cr, Fe, La, Mn, Na, Sc, Sm, V, W. A qualitative discussion regarding the passing of so me elements with different chemical affinity for oxygen compared to th at of iron, from the raw materials to slag or to finite products is pr esented.
