The thermal behaviour of Co(II), Ni(II) and Zn(II)-containing zirconium phosphate of α type was investigated. XRPD analysis
revealed that, for the samples containing Co(II) or Ni(II), the first reflection of the solid phase is split into a doublet.
In contrast, when Zn(II) is present, a single solid phase system is formed. The thermal behaviour of the materials followed
this sequence. For the samples containing Co(II) or Ni(II), phase-transition processes were found and there was also a loss
of crystal water, but for the sample containing Zn(II) there was only one endothermic effect, which corresponded to the decomposition
of phosphate groups.
