Conclusions

The authors investigated the influence of temperature, ranging from room temperature to 1500°K, on the thermal conductivity and electrical resistivity of sintered tungsten specimens with porosities between 0 and 45%. General laws governing the dependence of the thermal conductivity and electrical resistivity of tungsten on temperature and porosity have been established. The possibility of calculating these parameters at various temperatures and specimen porosities from unified conduction formulas has been analyzed.
