Is there any way to find a latent heat of fusion and vaporization of ZrB2-SiC composite?
Any lead would be appreciated.
Thank you.
To do this properly, you need the reference enthalpies and heat capacities of the solid, liquid, and gas forms. I suspect you know this and do not have this information. If you know the melting and boiling points, you can estimate the reference values from a Gibbs Energy analysis (melting point is when the Gibbs energy of the solid and liquid are the same and less than that of the vapor and boiling point is where the Gibbs Energy of the liquid and gas are the same and less than that of the solid). However, you cannot estimate the reference enthalpy and entropies for all three phases (you need both for a Gibbs energy analysis) from just two data points. There are group contribution theories and some quantum-chemistry-based partition function approaches to estimating these if you know the structure well enough.
