Synthesis, Ion Mobility, and Phase Transition in the (NH4)6LiHf2Zr2F23 Compound
- 1. Russian Academy of Sciences, Institute of Chemistry, Far East Branch (Russian Federation)
Description
Ion mobility and a phase transition (PT) in the compound (NH4)6LiHf2Zr2F23 are studied using 1H NMR, 19F NMR, XRD, and DSC methods. The types of ionic motions in the fluoride and ammonium sublattices of this compound are determined at 150–450 K; their activation energies are estimated. It is shown that an order-disorder PT occurs in this compound at 400–450 K to form a metastable high-temperature modification, where ionic motions are represented mainly by the diffusion of fluoride and ammonium ions.
