摘要/Abstract

摘要： 以分析纯Al(NO₃)₃·9H₂O, (CH₂)₆N₄和粒径为30 nm的SiC粉末为原料, 采用溶胶-凝胶(sol-gel)方法制备干凝胶, 经煅烧合成Al₂O₃-SiC纳米陶瓷粉, 利用真空热压装置对粉末进行烧结. 通过X射线衍射(XRD)、扫描电镜(SEM)和维氏硬度实验分析了不同SiC含量和不同烧结温度的Al₂O₃-SiC陶瓷样品的结构、形貌、晶粒尺寸和硬度, 并研究了其机理.

关键词: 溶胶-凝胶方法, Al₂O₃-SiC纳米复合陶瓷, 烧结

Abstract: A dry gel was prepared from Al(NO₃)₃·9H₂O, (CH₂)₆N₄ and SiC powder with a particle size of 30 nm via the sol-gel processing. Al₂O₃-SiC ceramic nanocomposites were obtained from the dry gel by means of vacuum heat-pressing technique. X-ray diffraction, scan electron microscopy and hardness experiment were used to analyze the structure, morphology, grain size and hardness of the Al₂O₃-SiC nanosized ceramic composites with different contents of SiC particles sintered at different temperatures.

Key words: sol-gel processing, Al₂O₃-SiC ceramic nanocomposites, sinter
