WebTo obtain a precise analysis of the temperature–dependent phase evolution during oxidation, coating powders were annealed in air between 100 °C and 1000 °C. Simultaneously, 2D XRD patterns were recorded in ~2 °C increments, which were subsequently evaluated using parametric Rietveld refinement. The results were … Web321 25K views 3 years ago X-ray Diffraction In this video, I will both show and tell you how to perform phase quantification with Rietveld refinement using HighScore Plus.
