sintered alumina 中文意思是什麼
-
Available standard ma - spinel bricks differ mainly in the type of magnesia and in the amount and type of their alumina carrier ( sintered and fused ma - spinel , calc. alumina , white fused alumina , etc
目前各種標準的鎂鋁尖晶石磚主要在氧化鎂的數量、種類和它們鋁載體的種類(燒結和電熔鎂尖晶石、鈣,氧化鋁,白電熔等)方面有很大的不同。 -
Sintered magnesia - alumina spinel
燒結鎂鋁尖晶石砂 -
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。 -
Sintered alumina and spinels
燒結氧化鋁和尖晶石 -
Updated patented technology of nuclear industry : inorganic membrane preparing process is adopted together with double - face and micropore ceramic board sintered with silicon carbide or alumina, which has a good resisting performance against friction and corrosion
核工業先進的專利技術:應用無機膜制備工藝,並採用耐磨耐腐性能良好的碳化硅或氧化鋁燒結成雙面微孔陶瓷板。
