Anisotropic thermal conductivity in Li2TiO3 ceramic breeder materials
M Sanjeev and MR Gilbert and ST Murphy, FUSION ENGINEERING AND DESIGN, 170, 112710 (2021).
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.
