摘要
随着5G时代的到来,氧化锆陶瓷材料凭借其断裂韧性好、强度高、耐磨损、低电磁屏蔽等优良的机械、物理性能成为精细陶瓷领域的研究热点。纳米氧化锆粉体的粒度、表面形貌及其稳定性直接影响着所制备的氧化锆陶瓷的质量。笔者按照固相法、液相法、气相法等分别介绍了几种常见纳米氧化锆粉体的制作工艺,分析比较了不同工艺方法的优缺点,重点评述了解决纳米钇稳定的氧化锆粉体(YSZ)容易发生团聚、与有机物亲和性较差等问题的表面改性技术。
With the advent of the 5G network,zirconia ceramic materials have become one of the research hotspots in the field of fine ceramics,due to their superior mechanical and physical properties such as good fracture toughness,high strength,wear resistance and low electromagnetic shielding.The properties of zirconia products are directly affected by the particle size,surface morphology and stability of nano-zirconia powder.In this paper,the solid phase method,liquid phase method,as well as gas phase method for preparing nano-zirconia powders are introduced respectively.The advantages and disadvantages of them are summarized.Finally,the surface modification technology for agglomeration and poor affinity with organic substances of Nano-yttrium stabilized zirconia powders(YSZ)are reviewed in detail.
