Abstract

The compounds Bi1.5Lu0.5O3 and Bi1.5Lu0.4In0.1O3, which hold promise as electrolytes of solid oxide fuel cells, were prepared using solid-state reactions. Their formation enthalpies and lattice enthalpies were determined using solution calorimetry. It was shown that the absolute value of the lattice enthalpy increases from Bi1.5Lu0.5O3 to Bi1.5Lu0.4In0.1O3, which correlates with a decrease in the ionic radius from lutetium to indium.
