Summary - Thermal Conductivity of Zirconium

A correlation for the thermal conductivity of zirconium as a function of temperature has been developed from a statistical analysis of zirconium thermal conductivity and thermal diffusivity measurements from 1951 to present. The data fit are summarized in Table 1. The recommended equation for the thermal conductivity of zirconium in W/m*K from 298 through 2000 K is: 


k = 8.8527 + 7.0820*10-3 T + 2.5329*10-6 T2 + 2.9918*103 T-1

This equation fits the 275 data with a multiple correlation coefficient, R, of 0.895 and a standard deviation of 1.73. One standard deviation uncertainties of this fit to the data range from 5 to 9.5%, depending on temperature. The recommended values of thermal conductivity of zirconium as a function of temperature are given in Table 2. The data and the fit with 1 standard deviation uncertainties are shown in the graph.
