Standard molar enthalpy of formation of Li₂ZrO₃

Nuclear fusion is a potential source of energy in the coming years with less environmental impact and reduced burden of nuclear waste management. In situ production of tritium in D-T based fusion reactor can be achieved through tritium breeding blanket modules (TBM) which uses lithium based ceramics as solid breeder materials. Lithium zirconate, Li₂ZrO₃, is one of the most promising candidates for tritium breeding materials to be used for the blanket of a nuclear fusion reactor. The thermodynamic stability of Li₇ZrO₃ is required for its usage at very high temperature. However, thermodynamic properties of Li₂ZrO₃ have not been reported. In this paper, the standard enthalpy of formation of Li₇ZrO₃ was determined
