The grain-size effect on thermal conductivity of uranium dioxide [PDF]
Journal of Applied Physics, 2019 We have investigated the grain-boundary scattering effect on the thermal transport behavior of uranium dioxide ( UO 2). The polycrystalline samples having different grain-sizes (0.125, 1.8, and 7.2 μ m) have been prepared by a spark plasma sintering ...
