液态Al氧化的环境透射电镜观察
DOI: 10.3724/SP.J.1037.2013.00165, PP. 953-958
Keywords: 液态Al,氧化,α-Al2O3,环境透射电子显微镜
Abstract:
为研究液态Al初期氧化产物的相组成及其氧化机理,采用环境透射电镜(E-TEM)对纳米Al粉末在720℃时的氧化进行了原位观察.差热分析(DTA)和TEM形貌观察结果表明,纳米Al粉末表面存在5—6nm厚的非晶Al2O3膜,该非晶膜在350—550℃间转变为γ-Al2O3.纳米Al粉末在10-4Pa高真空下熔化后冷却,可以得到无氧化膜的固态Al.再次熔化后的Al在720℃,10-2Pa氧分压下氧化,直接形成棒状的纳米α-Al2O3.同时,XRD检测结果表明,熔融的块状金属Al在720℃,10-2Pa氧分压下氧化,也得到α-Al2O3.液态Al的这种特殊氧化结果与其液态结构以及液态Al蒸发成气体再氧化有关.
