Phase Contacts between Particles in Disperse Structures

1 PHASE CONTACTS BETWEEN PARTICLES IN DISPERSE STRUCTURES 

The minimum value of the strength of the phase contacts can be estimated as

Although gradual transition is possible, the experiments show that in most cases this process is abrupt. This is the case when the formation of phase contacts is associated with the need to overcome the energy barrier defined by the work of formation of a nucleus of a contact, that is, of a primary bridge connecting two particles.
