| 摘 要： | 氧化锆(ZrO2)陶瓷具有出色的机械性能, 但其应用受到低热导率(Thermal Conductivity, TC)的限制。本研究设计并通过微波烧结制备了高热导率氧化锆-氮化铝(AlN)复合陶瓷, 优化制备条件后, 抑制了两种物质之间的反应, 获得了致密的复合陶瓷(相对密度>99%), 详细研究了该复合陶瓷的组织演变、热学性能和力学性能。研究结果表明, 随着AlN含量的增加, 复合陶瓷的室温下热导率、热扩散系数和热容增加, 分别达到41.3 W/(m·K)、15.2 mm2/s和0.6 J/(g·K)。这种具有高热导率和抗热震性的ZrO2-AlN复合复合陶瓷在能源系统的高温热交换材料领域具有广阔的应用前景。 |

| Abstract: | Zirconia (ZrO2) ceramics have excellent mechanical properties, but its application is limited by ZrO2-AlN low thermal conductivity (TC). Zirconia-aluminum nitride (AlN) composite ceramics ZrO2-AlN with high TC were designed and successfully fabricated by microwave sintering. After optimization of preparation conditions, the reaction between two substances was inhibited and the dense composite (relative density>99%) was obtained. The microstructure evolution, thermal behavior and mechanical properties were investigated in detail. The room temperature thermal conductivity, thermal diffusion coefficient and thermal capacity of ZrO2-AlN composites increase with AlN content increasing, reaching 41.3 W/(m·K), 15.2 mm2/s and 0.6 J/(g·K), respectively. Such ZrO2-AlN composites with high thermal conductivity and improved thermal shock resistance have broad application prospects in the field of high temperature heat exchange materials of energy systems. |
