Hello everyone,
I am trying to run Rietveld refinement on my sample which has two phases. The primary phase is quite dominant with most of the peaks, but there is only one peak of the secondary phase. I read somewhere that Rietveld refinement is not possible/will not yield good results if I run refinement on a pattern with les number of peaks. Can anyone please clarify whether I can run the refinement on a pattern with just one secondary peak .
My scan is from 10 to 70 degrees with a step size of 0.0168.
Hello, Vignesh.
A secondary phase with only one peak is quite problematic because we may not be able to identify it. But if you have a clue about it, we may try to find it.
Best regards
Ricardo Tadeu
Vignesh Radhakrishnan I am using the GSAS, an open-source Python-based software for calculating the phase fraction (wt. fraction). Some of my tutorials may help you do these calculations. One of my such tutorials in which I have refined a sample with two phases is at https://youtu.be/Z_aWz7Tx0Pw. Thanks
