The paper presents the application of an improved procedure for oxide speciation in steels by temperature ramped inert gas fusion technique on commercially available instruments. Main steps of analysis, data processing and interpretation of the results are described. The effects of instrumentation and auxiliary materials on the evolution kinetics of oxygen during an analysis are emphasised. The procedure is applied to determine the content of alumina and spinel species in high‐carbon steels, attested as reference materials. The results of the gas fusion technique are correlated to those of the chemical analysis and scanning electron microscopy equipped with energy dispersive X‐ray detector.
