Abstract

This paper is a review of the Soviet fundamental investigations on zirconium dioxide, ZrO2-based compounds and solid solutions as regards the tasks of high-temperature technics. The review covers a period of recent 20–30 years and is mainly based on publications in the Soviet magazines such as the “Proceedings of the Academy of Sciences of the USSR” (Doklady Academii Nauk SSSR), “Journal of Applied Chemistry” (Zhurnal Prikladnoi Khimii), “Inorganic Materials” (Izvestiya Akademii Nauk SSSR, Neorganicheskie Materialy) and “Refractories” (Ogneupory). The paper gives an account of research work including studies of the structure of zirconium dioxide, its polymorphic transformations, the influence of various impurities and other conditions on these transformations as well as investigations of the systems containing ZrO2 and refractory oxides of elements of groups II, III, IV and V of the periodic system. It is also concerned with problems of the mechanism and kinetics of interaction between oxides in ZrO2-containing systems. The second part will be devoted to applied investigations directed towards the elaboration of the synthesis processes of zirconia materials, the preparation of ceramic materials from them, the study of the relations between composition, structure and physicochemical properties. The third, concluding part, will contain information about the elaboration of several concrete technical materials for various purposes and their properties.
