Abstract Quantitative analyses of mixture composed of iron oxides and metal iron were investigated by means of powder X-ray diffraction and chemical analysis methods for iron oxides reduction by H2 and CO, respectively. The coefficients of quantitative molar intensity ratio of ferrite (αFe), austenite (γFe), iron carbide (Fe3C), magnetite(Fe3O4) and hematite (Fe2O3) to wustite (Fe0.947O) are 0.56, 0.56, 0.52, 0.87 and 2.57 respectively. The degrees of metallization and reduction of iron oxide were calculated according to these coefficients.
