Abstract
Abstract Nanoparticle zinc phosphate dihydrate was prepared by solid-state reaction at ambient temperature from Na3PO4·12H2O and ZnSO4·7H2O, and characterized by X-ray, Raman, FT-IR spectra and TEM. Thermochemical study was performed by a RD496-III microcalorimeter at 298.15 K. The results reveal that the obtained product is Zn3(PO4)2·2H2O with spherical shape and particle size is between 40–50 nm. The standard enthalpy value for above reaction is calculated as − 45.793 kJ·mol− 1. The standard enthalpy of formation for zinc phosphate dihydrate is recommended as − 3788.607 kJ·mol− 1.
