Systems on the basis of oxide of cerium found broad application in an automobile catalysis. These materials are capable to absorb and emit oxygen from the lattice and thanks to it to increase overall performance of precious metals. Today of these systems are demanded much regarding heat stability. The main ways of increase in heat stability is the increase in a share of zirconium in solid solution and an additive of modifying rare-earth elements. In this paper some basic patterns in the synthesis of solid solutions based on zirconium and cerium by the method of hydrothermal treatment, identified major trends in increased thermal stability of the specific surface and to maintain homogeneity of the phase composition. Influence of rare-earth elements on physical and chemical properties of these solid solutions is also investigated.
