Abstract
Hydrothermal phase stability studies of tungsten trioxide under water vapour pressure showed a monoclinic to tetragonal phase transformation with a nearly pressure independent invariant equilibrium boundary line. The standard thermodynamic data for the tetragonal form of WO3 obtained from the experimental PT points on the equilibrium transformation boundary are: DELTA-G(f)0 = -759.743 kJ/mol., DELTA-H(f)0 = -836.598 kJ/mol., S(f)0 = 82.59 J/mol.deg.
