Thermal Conductivity of Zirconium - Nuclear Power

Thermal Conductivity of Metals. Metals are solids and as such they possess crystalline structure where the ions (nuclei with their surrounding shells of core electrons) occupy translationally equivalent positions in the crystal lattice.Metals in general have high electrical conductivity, high thermal conductivity, and high density.Accordingly, transport of thermal energy may be due to two effects:
