Abstract:
A study of the aggregative stability of the CeO$_2$-ZrO$_2$ system was carried out in various pH ranges of the medium. To create a mathematical model of the stability of aggregates, the generalized DLVO theory was taken. The parameters of the structural component of the potential energy of particle interaction are determined using the principle of minimum entropy production. The limiting particle sizes of an an aggregatively stable system are determined.
Keywords:
coagulation kernel, principle of minimum entropy production, aggregative stability, oxides.
