Metal-ceramic interface interactions wetting and interfacial energies

3 Metal-ceramic interface interactions wetting and interfacial energies 

The phenomena which occur in metal-ceramic interface interactions are of great importance in catalysis. There are two types of interactions those which depend on the epitaxy between the metal and the support and those which are independent of it. Strong metal-support interactions are described by the term SMSI. 

In the equation, generally if the magnitude of the right-hand side exceeds one, the wetting angle would be complex with crystallite (or particle) spreading
