pure alumina 中文意思是什麼
pure alumina
解釋
純氧化鋁-
Nanometer pore arrays alumina films were prepared by anodizing of highly pure aluminum foils in sulfuric and oxalic acid solution. the porous alumina layers were detached from the al substrate by using step - down voltage or solution method
在草酸和硫酸溶液中，通過陽極氧化高純鋁片的方法制備了納米氧化鋁膜孔陣列，用階梯降壓法或溶解法將氧化鋁膜層和鋁基底分離。 -
The results show that the a - phase - transformation of pure aach can be completed by heating at 1200 ? for two hours. but under this temperature, the alumina particles will be sintered together, which can lead to the formation of bough - like structures. and these bough - like structure will make the powder difficult to be dispersed
接著對碳酸鋁銨進行了焙燒實驗，研究了其在升溫過程中的相變行為，結果表明：純aach在1200保溫1 . 5h的情況下才能100轉變為氧化鋁，而在這樣高的溫度下，粒子之間會形成燒結頸，從而使粉體產物在形貌上出現所謂「樹枝狀」結構，給粉體使用時的分散帶來了困難。 -
By using the high pure alumina micro - powder ( > 99. 0 % ) and the polymorphous alumina fiber as materials, by adding alumina sulfate as the binder or polypropylene - amide as the disperser respectively, through mixing, dispersing, and compression molding, at different temperatures of 1200 c, 1350 c, 1400 c, 1500 c, and 1550 c with no pressure, the alumina fiber - alumina composites were made
本試驗採用高純氧化鋁微粉（ 99 . 0 ）和多晶氧化鋁纖維為原料，分別加入硫酸鋁和聚丙烯酰胺作結合劑和分散劑，經混合、分散、壓力成型及在1200 、 1350 、 1400 、 1500 、 1550下無壓燒成制得氧化鋁纖維? ?氧化鋁復合材料。
