Thermal analysis of formation of ZrO2 nanoparticles under hydrothermal conditions

The formation of ZrO 2 nanoparticles during the hydrothermal treatment of zirconium oxyhydroxide has been investigated depending on the chemical and thermal history of the initial material. It has been shown that the crystallization of c(t)-ZrO 2 and m-ZrO 2 under hydrothermal conditions proceeds virtually simultaneously, and the amount of one or another polymorph depends mainly on the ratio of rates of these processes.
