Promethium(III) phosphate is an inorganic compound, a salt of promethium and phosphate, with the chemical formula of PmPO₄. It is radioactive. Its hydrate can be obtained by precipitation of soluble promethium salt and diammonium hydrogen phosphate at pH 3~4 (or obtained by hydrothermal reaction ^[2]), and the hydrate can be obtained by burning at 960 °C to obtain the anhydrous form.^[1] Its standard enthalpy of formation is −464 kcal/mol.^[3]
