查询词典 crystal particle

But when Fe/D113 precursor is pyrolysed in the range of 400-700℃, the crystal structure of the iron particle is different. The products are mainly iron oxides andα-Fe as Fe/D113 precursor pyrolysed at 500℃, and as the pyrolytic temperature increases to the range of 600-700℃,α-Fe and Fe_3C are observed. Meanwhile, Al_2O_3、MgO、MgAl_2O_4 were observed in Al/C, Mg/C, Al-Mg/C which were prepared from D113 resin at 1000-1300℃.

而在同样的条件下热解载铁树脂(Fe／D113)，热解产物中铁的晶体结构与热解温度有关，400℃热解产物为铁的氧化物；500℃热解产物为体心立方结构的单质铁；600-700℃的热解产物为bcc单质铁和铁的碳化物(Fe_3C)。1000-1300℃热解含Al、Mg及Al-Mg的D113树脂制得的Al／C、Mg／C、Al-Mg／C材料中Al、Mg主要以Al_2O_3、MgO、MgAl_2O_4形式存在。
