Abstrakt: X-ray powder diffraction methods of phase quantification were adapted and compared to mixtures of β-Si3N4 and β-SiC. Multiline mean-normalized-intensity methods and whole pattern analysis (Rietveld) both have advantages and disadvantages over each other. Satisfactory results (less than 3% absolute deviation) can be achieved in minimal time using intensity normalization methods. Phase quantification using the Rietveld method requires significantly longer measuring time, evaluation time and expertise to obtain the same results. [ABSTRACT FROM AUTHOR]
