Abstract
Possibility of the low-temperature synthesis of zirconium dioxide nanopowder stabilized with yttrium (8 mol. %) from a mixture of hydrated zirconium oxynitride and yttrium carbonate mechanically activated in a continuous-type mill. It was shown that the powder formed even at 600 °С is easily moulded by dry pressing after disaggregation; its density after sintering is close to the theoretical value.
