Synthesis of nanocrystalline zirconia-based powder for surgery implants and study of radionuclides content in it
Nanocrystalline powder of ZrO₂ (5 % Y₂O₃, 3 % CeO₂) has been synthesized. The powder is developed for manufacture of ceramic implants for bone surgery. Physico-chemical properties of the powder and its radioactivity have been examined. It is shown that the proposed technology allows to produce the n...
