  • X-ray Powder Diffraction (XRD) - Carleton College

    2004-8-27 · Phases were determined because of their influence on the end properties of refractory materials. Five analytical programmes for XRF analysis and an XRD analysis method were established. We optimized sample preparation in the form of beads for the XRF measurement by determining the most appropriate sample/flux ratio for each type of refractory.
