摘要

3Y-TZP是一种高性能的先进陶瓷材料，在工业和生物医学领域有着广泛的应用。然而，3Y-TZP陶瓷可能因此面临低温老化问题，限制了其在医疗领域的发展。本研究旨在探讨一定量的CeO2掺杂对3Y-TZP陶瓷整体性能的影响。采用共沉淀法制备3Y-TZP粉体。随后与不同比例的氧化铈粉混合。Johnson-Mehl-Avramorow-Kolmogorov （JMAK）方程的拟合结果表明，CeO2掺杂是增强其抗衰老性能的有效添加剂。该材料具有良好的生物相容性，在口腔医学领域具有广阔的发展前景。

Mechanical, low temperature degradation and biocompatibility of Ce-doped dental 3Y-TZP ceramics

3Y-TZP is a high-performance advanced ceramic material, which has a wide range of applications in industrial and biomedical fields. However, 3Y-TZP ceramics may face the problem of low-temperature aging due to this, which limits its development in the medical field. This study is aimed at investigating the effect of a certain amount of CeO₂ doping on the overall properties of 3Y-TZP ceramics. The 3Y-TZP powder was prepared using the co-precipitation method. Subsequently it was mixed with various proportions of cerium oxide powder. The fitting results using the Johnson-Mehl-Avramorow-Kolmogorov (JMAK) equation indicated that CeO₂ doping was a useful addition to enhance its anti-ageing properties. The modified material was found to have good biocompatibility, which suggests a promising outlook for its development in the field of dentistry.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
