| 摘 要： | 利用透射电子显微镜观察热蒸镀法制备的铝超微粒子的形状呈杆状,其纵向粒径分布呈对数正态分布、横向粒径分布呈算术正态分布,纵、横向粒径的比值分布呈对数正态分布;当粒径在9.0～53.4nm之间时,其熔点为580℃,熔点降低80℃.

| Abstract: | In the paper, size distribution for Al ultrafine particles prepared by evaporating up process is discussed through TEM. Longitudinal size and ratio of longitudinal to transverse size for Al ultrafine particles show out the log-normal distribution. But transverse size shows out Gaussian distribution.. Finally, variation for melting point of Al ultrafine particles is discussed. |
