Hi,
I want to know the enthalpy of formation of Ga2O3 and Ga2O at low pressure (ultra high vacuum) and high temperature.
Temperature seems easy, but I'm not sure how to get the enthalpy values for low pressures.
Does anyone know if there are books with enthalpy - pressure diagrams of these compounds?
It should be also possible to calculate it from the value at atandard conditions using ∂H/∂P=(V−T∂/V∂T)dP, but one needs a PVT relation. For Ga2O maybe the van der Waals equation for non-ideal gases? And for Ga2O3?
Cheers,
Julius
