Thermal conductivity of non-stoichiometric Li2TiO3

The transfer of heat through the breeder region of a future fusion reactor is a key component of its thermal efficiency. Development of advanced ceramic breeder materials based on Li2TiO3 seek to exploit its ability to accommodate significant non-stochiometry, however, it is not clear how deviations for the 50:50 mix of Li2O and TiO2 will affect key properties of the material, including the thermal conductivity. Therefore, in this work molecular dynamics simulations are employed to examine how the thermal conductivity of Li2TiO3 changes with stoichiometry. The results suggest that while there is a significant decrease in the thermal conductivity at room temperature, at higher temperatures the impact of deviations from stoichiometry is limited.
