Аннотация

The standard formation enthalpy of the Bi12.5Er1.5CoO22.3 phase has been determined as following: ΔfH0(Bi12.5Er1.5CoO22.3, s, 298.15 K) = −5203.9 ± 14.5 kJ mol–1. Solution calorimetry, using 1 mol dm–3 HCl as a solvent, has been used to study the thermochemistry of Bi12.5Er1.5CoO22.3. The lattice energy for Bi12.5Er1.5CoO22.3 has been calculated on the basis of Born-Haber cycle using the standard formation enthalpy of the phase and literature data. For the first time, we measured the magnetic characteristics of Bi12.5Er1.5CoO22.3 and established that the Bi12.5Er1.5CoO22.3 phase has paramagnetic properties.
