Thermal Conductivity of Sodium-Potassium Alloy (77.7wt.-% Potassium).

摘要

The thermal conductivity of sodium-potassium alloy, 77.7 wt. %K, has been determined between 157 and 676 deg C. The conductivity curve of this alloy increases from 0.2393 watts/cm-deg C at 157 C to a maximum of 0.2618 watts/cm-deg C at 445 deg C and then decreases to 0.2563 watts/cm-deg C at 676 deg C. A graphic correlation of these results with those of two other previously reported sodium-potassium alloys is presented. (Author)
