Neutron scattering from films of pellicular zirconium phosphate

Abstract

Neutron-scattering studies have been undertaken in the investigation of crystalline α-zirconium phosphate [Zr(HPO₄)₂·H₂O, α-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 α-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 °C.
