I have synthesized these two new materials in our lab. The first material (HEBM20hrs_SPS400C ) is single phase Ba5(VO4)3I and the second material (HEBM30hr_200_1hr) has two phase Ba5(VO4)3I, BaV2O6, and small portion amorphous. In the Highscore Plus database, I found Ba5(VO4)3Cl or Br materials with same structure. So I choose their PDF card to produce these two HPF files for the Rietveld refinement. But I couldn't refine well. I tried both in automatic and manual mode by changing different parameter as I watched some tutorial videos but it's not changing.
Here I tried these PDF card references (PDF Card - 00-059-0654_Ba5(VO4)3Cl, PDF Card - 00-049-0525_Ba2V2O6). Can you please help me out with the refinement for both materials with structural data and calculate the percentage of each phase of the second material?
Please send me to my email: [email protected]
Thanks a lot,
