焙烧时间 meaning in English
roasting time
Examples
- It ' s obtained that ph = 6 . 5 is a suited ph value for getting ideal product with good properties . the calcinate temperature is the key factors to transform the precursor to a pure product with spinel structure
研究了不同的工艺条件如溶液ph值、焙烧温度、焙烧时间、焙烧方式、 li / mn的比值对产物结构的影响。 - 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
前驱体的焙烧温度和焙烧时间对limn _ 2o _ 4样品的晶相结构有很大的影响，焙烧温度高于750时，应采用分段焙烧工艺以防止局部高温形成li _ 2mno _ 3杂质。 - Through the synthesis of licoo2 by using non - water dispersant and two - step roasting , influences of microstructures of precursor , the roasting temperature and the reaction time on the electrochemical properties of licoo2 were studied . it indicated that co3o4 with nano - crystalline have very good electrochemical property , and can shorten solid reaction time
02的制备工艺，考察了不同微结构的co30 ;先驱物，焙烧温度和焙烧时间等工艺条件对licoo ，电化学性能的影响，其中以纳米晶co3o ;制备出的licooz表现出优良电化学性能，且大大缩短了反应时间。 - The characteristic of different products at different calcinating temperatures and time , ph value of solution , raw materials were investigated . the results show that perfect spinel li4mn5o12 crystals whose size belongs to nanometer can be obtained from the precursor of lithium manganese oxides after being calcinated . it is founded that calcinating temperature has great influence on the crystal structure of li4mn5o12 and the optimized temperature is 500
结果表明焙烧温度是影响产物结构性能的最重要的因素，最佳焙烧温度为500 ，温度小于200不能形成完整的尖晶石结构，而焙烧温度超过500产物会发生分解；综合考虑焙烧时间最佳为8小时；溶液ph值也是影响产物性能的因素之一，实验证明前驱体合成ph = 9 . 0最佳；另外不同的原料也会影响产物的结构，考察了不同锂源的影响，选择li _ 2co _ 3为最佳锂源。 - ( 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 )对纳米二氧化铈制备过程中可能的一些影响因素(反应组分的浓度，沉淀剂的加入量，焙烧温度，焙烧时间等)进行了研究，并通过tg ? dta分析手段对前驱物进行热重分析；用xrd 、 sem及tem等测试手段对产物的粒度和晶型进行分析；探索了各个因素对纳米二氧化铈制备的影响及各因素间的交互作用；确定了在该试验条件下制备纳米二氧化铈比较优化的制备条件。
