NEW DIFFRACTION DATA Characterization of δ-KZnPO4 by X-ray powder diffraction

The structural parameters of a second low-temperature form of KZnPO4 have been refined using Rietveld analysis of X-ray powder diffraction (XRPD) data. This form of KZnPO4 is isostructural with NH4ZnPO4I and has previously been denoted as KZnPO4II. This article uses the notation δKZnPO4, to be consistent with the α, β, and γ notation commonly used for other KZnPO4 phases. © The Author(s), 2021.
