Hi, everyone?
I am a graduate student in univ. of cincinnati.
Recently, I knew this wonderful method and want to try structure
refinement of Zirconia-doped-Barium-Titanate system with GSAS.
I want to calculate the bond length and angle which is expected to
change with zirconia doping
concentration changing.
the c/a ratio, as I observed, approached to 1.00, i.e. cubic, from
tetragonal.
But due to the lack of the knowledge, I faced a trouble to
Rietveld-refinement my material.
,so If there is anyone who did or know about this barium titanate system
w.r.t Rietveld method,
please let me know, then I will be so grateful.
Thank you so much..
the following is the XRD I used and will use :
