Thermal Conductivity of Zirconium

Thermal Conductivity of Zirconium Zirconium is a lustrous, greywhite, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion.
