[Study on quantificational analysis method for the non-crystalline content in blast furnace slag].

Quantificational analysis method for the non-crystalline and crystalline contents in blast furnace slag was studied by means of X-ray diffraction. The process of quantificational analysis method includes standard samples preparation, samples preparation, X-ray diffraction measurement and data treatment. The data treatment includes integration areas of non-crystalline curve and crystalline peaks in certain diffraction angle range, linear fitting and quantificational coefficient determination.

[A new method for the measurement of degrees of reduction and metallization of iron oxide].

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 (alphaFe), austenite (gammaFe), iron carbide (Fe3C), magnetite (Fe3O4) and hematite (Fe2O3) to wustite (Fe(0.947)O) are 0.
