Quantitative analysis of free-lime (CaO) in the slag by X-ray diffraction (XRD) method was considered experimentally. CaO included in the slag was not pure CaO because X-ray diffraction peaks of CaO in the slag shifted from that of reagent CaO. The standard addition method was applied for quantitative analysis by XRD. In order to evaluate suitability, quantitative values obtained from XRD were compared with chemical analysis values obtained from ethylene glycol extraction method. Both values showed good relation. It was proved that a linear relation between XRD values and chemical analysis values by Pearson product-moment correlation coefficient.
