evaluate the proportion of crystalline and amorphous (glassy) phases in fly ashes produced
in pulverized-coal-combustion (PCC) power plants. The quantification of amorphous phases
through the Rietveld method is most usually carried out (i) by using an internal standard or
(ii) by using a poorly-crystalline phase to represent the amorphous phase in the lineshape
calculations. In the present work, we explore the usefulness of an alternative method that …
