Abstract

The high anisotropy in the thermal conductivity of lithium metatitanate, Li2TiO3, is shown using the classical simulation method of Molecular Dynamics (MD). The thermal conductivity along the z-direction is markedly lower than that in x and y. This characteristic could be exploited in the fabrication of breeder blanket design to favourably adjust the thermal conductivity of Li2TiO3 by ensuring alignment along x or y. This work sets the foundation for investigating the effect of defects on the thermal conductivity of Li2TiO3, as anticipated to be formed during the lifetime of a breeder blanket.
