General Description

Thorium dioxide, also known as thorium(IV) oxide, is a radioactive chemical compound that is used as a fuel in nuclear reactors. It is a solid, pale yellow substance that is insoluble in water and has a high melting point. Thorium dioxide is known for its high thermal stability and is often used as a coating for high-temperature applications, such as in the manufacturing of gas mantles and incandescent gas lamps. It is also a potential alternative to uranium dioxide as a fuel for nuclear reactors, as it has a higher thermal conductivity and a potentially lower risk of nuclear proliferation. However, thorium dioxide is also a source of concern due to its radioactivity and potential for environmental and health hazards if not handled properly.

In this research, the reverse non-equilibrium molecular dynamics is employed to investigate the effect of vacancy and substitutional defects on the thermal transport in thorium dioxide (ThO2). Vacancy defects are shown to severely alter the thermal conductivity of ThO2. The thermal conductivity ...detailed
