Abstract
On the basis of an analysis of obtained results and literature data, we propose a kinetic model of the interaction of components in the Li[Ca]–V[O] system. The model demonstrates the cyclicity of the process. Each cycle consists of the following stages: (1) transfer of oxygen from vanadium to lithium, (2) growth of an external CaO oxide layer with simultaneous dissolution of dispersed titanium oxides in the matrix and transfer of oxygen and titanium into the solid solution, (3) penetration of the liquid metal into the solid one by the reaction-diffusion mechanism, and (4) decay of metastable triple oxide and restoration of an external CaO oxide layer. Within the framework of the model proposed, we develop the concept of work of the CaO oxide coating under isothermal conditions and in the heating–cooling mode.
