polymorphic transition中文什么意思
例句與用法
- Compared with 3 % , the temperature of polymorphic transition between anatase and rutile of 8 % which is the molar quantities of mixed rare earth is a little lower . the calcination temperature is a main reason which influences the structure of phase
摻入鏑的含量8時(shí)，銳鈦礦相向金紅石相的轉(zhuǎn)變溫度與3相比有所降低，所以煅燒溫度是影響產(chǎn)物結(jié)構(gòu)的主要原因。 - When the molar ratio of titanate , water and ethanol is 1 : 2 . 5 : 25 , ph value is controlled about 4 . 0 , calculation temperature as 600 , and calcinations time is two hours , the ultrafine product is prepared . the temperature of polymorphic transition between anatase and rutile of dy - doped tio2 is higher than the temperature of transition of pure tio2 . the rare earth improves the hot stability of the power
研究發(fā)現(xiàn)，當(dāng)鈦酸丁脂、水、和乙醇的物質(zhì)的量的比為1 ： 2 . 5 ： 25時(shí)， ph值控制在4 . 0左右，煅燒溫度為600 ，保溫2小時(shí)后獲得粒徑非常細(xì)小的不同化學(xué)計(jì)量比組成的氧化鈦和氧化鏑的復(fù)合氧化物。
