N2 - Knowledge about polymorphism is extremely important when using the materials. A large number of compounds are very similar in chemical composition form fundamentally different crystal structures both under ambient and high-temperature conditions and as a consequence demonstrate distinct physical properties. Here, phase transformations, thermal properties and crystal structure of the CaZn2P2O8 polymorphs (α-, β- and δ-modifications) were studied by in situ high-temperature (up to 1000 °C) powder X-ray diffraction (XRD) and single crystal XRD. During the studies crystal structure of δ-CaZn2P2O8 has been solved and refined for the first time (P21/c space group, a = 15.6900(9), b = 8.8091(5), c = 9.8229(5) Å, β = 93.210(5)°, V = 1355.5(1) Å3). The thermal expansion coefficients of α- and β-CaZn2P2O8 were calculated and compared with other isotypical compounds.
