摘要

The National Institute of Standards and Technology (NIST) Fly Ash Standard ReferencernMaterials (SRMs) have been investigated by Rietveld quantitative X-ray diffraction (RQXRD)rnusing varied experimental conditions. Conditions examined include the diffractometer slitrnconfiguration (variable or fixed divergence slits), internal standard, and radiation wavelengthrn(iron radiation or copper radiation). The slit configuration has little impact on the results forrnthese materials, while the choice of internal standard and the radiation wavelength both appear tornhave a significant impact on the results obtained.
