Effect of graphite and graphene oxide on thorium carbide microstructural and thermal properties.

ABSTRACT: Thorium carbide to be tested as target material for the production of ²²⁵Ac with the ISOL method, was produced via carbothermal reduction of ThO₂ nanoparticles by graphite and graphene oxide, respectively. The use of graphene oxide (GO) as carbon source resulted in a reduced reactivity compared to graphite, confirmed by the presence of unreacted ThO₂ mainly in the core of the samples. The reacted ThO₂ or ThC₂-GO showed a faster reactivity in air, mainly observed as ThC₂ amorphization. The specific surface area of the ThC₂-GO samples was almost doubled compared to ThC₂-graphite samples. The effect of these microstructural features was analysed in terms of thermal diffusivity and calculated thermal conduc
