    摘要:

    采用爆炸法制备了粒径为11.5~16.55 nm纳米多晶氧化锆粉末。借助热重分析(TG-DTA)、煅烧试验研究了气相氧化温度对最终粉体性能的影响,通过X射线衍射、拉曼光谱、透射电镜(TEM)等手段对前驱体和产品进行了表征。结果表明,改变氧化温度可实现对粉体晶相组成的控制,该法大大缩短了晶体高温生长时间从而有效抑制了纳米粉体团聚,所制备的粉末为为分散性良好的纳米四方/单斜氧化锆多晶。

    Abstract:

    Nanometer polycrystal zirconia powder of 11.5-16.5 nm was prepared by explosive detonation technique. The effects of gas oxidation temperature on the properties of the as-synthesized powder were studied by thermogravimetry (TG),differential analysis (DTA) and calcination experiment. X-ray diffraction (XRD),Raman spectrum and transmission electron microscopy (TEM) were used to characterize the precursor and the as-synthesized product,respectively. The crystal phase composition of zirconia can be controlled through adjusting calcination temperature. The agglomeration problem of product was controlled through shortening growth time.
