The results show that all of them have little different effect on the crystalline size of ultrafine powder of a - ahc ^, but they have greatly different effect on the secondary partical size. the azeotropic distillation is the most effective processing, it can prevent the formation of hard agglomerates and improve the sinter - ability of powder. the mechanism of drying stages preventing the formation of hard agglomerates has investigated
研究了三種不同的乾燥方法（直接乾燥法、酒精置換乾燥法和共沸蒸餾乾燥法）對粉體性能的影響。實驗表明三種乾燥方法對- al _ 2o _ 3粉體的一次粒徑的差別性影響不顯著，而對其二次粒徑的差別性影響則很顯著。 -
It is indicated that mechanical milling dramatically enhances the activity of the powder and thus making the solid state diffusion between the two elements much easier. on the other hand, green samples made of deep milled powders are hard to sinter to their densification
實驗結果表明，機械研磨由於顯著提高粉體活性而促進ni ， ti元素間的擴散相變，研磨程度越深，對固態反應相變的促進作用越大。
