I could not find an accurate value in the literature, would you know it?
I would need the polar and dispersive parts as well.
Thanks in advance.
Dear Antoine:
Surface energy is term chemical thermodynamics. This is not an exact definition of the term. There is surface energy change of Gibbs in the process. There is change in enthalpy of the surface. Change Gibbs surface energy is equal of the surface tension on change the surface area. Changing of surface Gibbs energy is equal change enthalpy + product of entropy changes multiplied by temperature. All changes are associated with the process. The tables give surface tension (Gibbs specific energy process). Details, please Gibbs energy? Enthalpy? Surface tension?
Best regards.
Dear Yuri,
thank you for your detailed answer.
I meant surface tension, in the form γ=γp + γd
where p stands for polar and d for dispersive.
just to add, there is no defined 'native silicon dioxide'. It is even difficult to obtain clean crystalline quartz surface.
Oxygen and silicon oxide form a covalent bond in silicon dioxide. The surface does not include polar and dispersion bonds.
Best regards.
