SOLUBILITY OF DEUTERIUM IN YSZ10 ZIRCONIUM DIOXIDE NANOPARTICLES

For cubic zirconia doped with yttrium oxide, data have been obtained that attest to the high sensitivity of the solubility of deuterium in nanopowders to oxygen deficiency in the volume of nanoparticles and to surface structural defects. The investigation is performed on nanopowders synthesized by laser sputtering of a ceramic target. An accelerating technique of nuclear reactions is used to measure deuterium concentration. It has also been found that the deuterium concentration on the surface of nanoparticles decreases when they are irradiated with deuterons, this effect being due to the selective sputtering of dissolved deuterium atoms by accelerator beam ions. It is concluded that investigations of deuterium solubility and ion sputtering of deuterium atoms by accelerated deuterons are an effective tool for obtaining information on the defect structure of oxide nanoparticles.
