This document describes methods for the determination of mineralogical phases often present as additives or reaction products in carbon containing or graphitic refractory products by X-ray Diffraction (XRD) using a Bragg-Brentano diffractometer. It includes details of sample preparation and general principles for qualitative and quantitative analysis of mineralogical phase composition. Quantitative determination of α-Si₃N₄, β-Si₃N₄ , AlN, aluminium metal, Al₄C₃ , silicon metal, boron carbide and BN are 3 4 3 4 4 3 described. The problems encountered with some determinations are highlighted.
