摘要：
The physicochemical properties of ZrO2-based composite in the ZrO2-Y2O3-CeO2-CoO system, which is intended for the development of bioinert implants, are examined. To produce the starting nanocrystalline powder, hydrothermal synthesis in alkaline medium and mechanochemical treatment were successively used. The samples were consolidated by cold uniaxial pressing, sintering in air, and barothermal treatment in argon. This resulted in the fine-grained composite consisting of (mol.%): 96.3 ZrO2-2.8 Y2O3-0.6 CeO2-0.3 CoO. The composite has properties that comply with international standards and is not prone to ageing.
