Dynamic synthesis of zirconium dioxide powders

We investigated the process of zirconium dioxide powder synthesis by shock wave loading of a porous metal and the subsequent dispersion. The synthesized powder consists of hollow spherical shells and highly porous conglomerates with a 500 $\mu$m mean dimension. The specific surface of the powder is independent of the particle size and is 1.25 $\pm$ 0.35 m$^2$/g. The tetragonal modification predominates for large dimensions, while the monoclinic is more common in the small. The possibility of stabilizing the oxides in the high-temperature phase is investigated.
