Abstract
Thermodynamic calculation on reduction of tungsten oxide in H2 atmosphere is carried out in this paper. The general calculation model of the standard free energy changes for reactions are established. Accurate calculation and plotting of the standard free energy changes, equilibrium constants and gas composition for preparing tungsten by reduction of tungsten oxide in H2 atmosphere are realized using the developed general computer program, especially for the polynomial integral and subsection integral operations.
