Thermodynamics of Wetting and Spreading

1 Thermodynamics of Wetting and Spreading. - The thermodynamics of wetting of a solid by a liquid is well established and discussed in detail in relevant textbooks. The same principles can be applied in the phenomenological treatment of the wetting of one solid by another solid, a phenomenon that also plays a major role in the redispersion of 

The overall change in interfacial-free energy AF is given by Equation (1)  

Interface-free energies are practically always unknown, is given by Equation 

Surface-free energies of several oxides, which bear relevance in the present context as either supports or active oxides, are summarized in Table 1 together with their bulk melting points T u and Tammann temperatures Tj = 0.5 T g,j.

The foregoing discussions on the thermodynamics of wetting and spreading are limited to systems which arc...
