焙燒段 的英文怎麼說
中文拼音 [bèishāoduàn]
焙燒段
英文
firing section-
Spinel limn2o4 begin to form at 350 with the sintering time of 4 hours because there are one li + and two mn2 + in one precursor molecule. when the sintering temperature is larger than 750, a specific sintering route is designed to avoid the formation of li2mno3 impurities
前驅體的焙燒溫度和焙燒時間對limn _ 2o _ 4樣品的晶相結構有很大的影響,焙燒溫度高於750時,應採用分段焙燒工藝以防止局部高溫形成li _ 2mno _ 3雜質。( 2 ) the affecting factors such as components in precipitation process, the add - on, add on of precipitator, calination temperature and calination time were studied in the preparation process of ceo2 nanoparticles. the tg was used to analyze the processor, the xrd, sem and tem were used to characterize the size of crystal type of products. by a series of designed experiments the interaction between different factors and impacts on the preparation of ceo2 nanoparticles were probed, and the optimum preparation condition was gotten
( 2 )對納米二氧化鈰制備過程中可能的一些影響因素(反應組分的濃度,沉澱劑的加入量,焙燒溫度,焙燒時間等)進行了研究,並通過tg ? dta分析手段對前驅物進行熱重分析;用xrd 、 sem及tem等測試手段對產物的粒度和晶型進行分析;探索了各個因素對納米二氧化鈰制備的影響及各因素間的交互作用;確定了在該試驗條件下制備納米二氧化鈰比較優化的制備條件。
