polymorphic transition造句

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
掺入镝的含量8时，锐钛矿相向金红石相的转变温度与3相比有所降低，所以煅烧温度是影响产物结构的主要原因。
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
研究发现，当钛酸丁脂、水、和乙醇的物质的量的比为1 ： 2 . 5 ： 25时， ph值控制在4 . 0左右，煅烧温度为600 ，保温2小时后获得粒径非常细小的不同化学计量比组成的氧化钛和氧化镝的复合氧化物。
