Neutron-scattering studies have been undertaken in the investigation of crystalline alpha-zirconium phosphate [Zr(HPO4)2.H2O, alpha-ZrP] and of films of pellicular zirconium phosphate (p-ZrP). In the inelastic neutron scattering (INS) spectra of p-ZrP films fewer peaks are observed than in the case of alpha-ZrP and intensities in the region 720-1120 cm-1 (associated with acid phosphate groups) are orientation dependent, Quasielastic broadenings are observed in scattering spectra from p-ZrP films at 70-degrees-C.
