There are many ways how elemental analysis (e.g. by XRF) can be used to guide the XRD phase quantification. This becomes especially relevant when using "2 in 1" equipment like "Thermo ARL 9000 Workstation". The XRD-XRF combination is often used (by various ways) in cement industry - you may search for references from this field for a good start.
The whole process becomes tricky when amorphous phase(s) is present as XRD obviously sees only crystalline part. Consequently, combining the two techniques, one can (often; by certain procedures) extract the amorphous phase content. _________________ Maxim V.
