Nanoparticles based on ZrO2 in the form of spheres, cylinders and agglomerates in the form of hollow micro-spheres were obtained. It is shown that the main factor in uencing on the formation of nanostructures based on zirconium dioxide under hydrothermal conditions is the chemical prehistory of the starting materials. The possibility of varying the synthetic parameters to obtain a zirconia-based material with high porosity and speci c surface area was shown.
Keywords: nanoparticles, hydrothermal synthesis, zirconia.
