powder-like structure 中文意思是什麼
powder-like structure
解釋
粉狀結構-
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。
