New Features in Chekcell and Rietica:What do we need from the diffraction data?

Accurate Unit Cell volumes to obtain the “equations of state” of the phases of interest (how the volume of the phases change with pressure and temperature)

T - RbClO4 = B2-RbCl + 2O2

4 R-KClO3 = 3 O-KClO4 + B2-KCl

O-KClO4 = B2-KCl + 2 O2

O2 from the differences in the unit cell volumes
