| 摘 要： | 在室温条件下对钛铁矿进行了注入H 2离子实验,结合透射电镜观察,研究了钛铁矿还原过程中的微观机理. 实验发现,注入H 2离子后,1-10]方向的金属铁晶体在1-4 3-1]方向的钛铁矿晶体上生成;在钛铁矿还原过程中,金属铁的(2-2-2-)或(222)晶面优先由钛铁矿的(42 6-4-)和(4-2-64)晶面转变而来,钛铁矿还原到铁的结构变化是一个渐变过程.

| Abstract: | H 2 ions were implanted into ilmenite at room temperature,and the microreaction mechanism during the reduction of ilmenite was investigated by transmission electron microscopy.The results indicate that during the course of reduction,metallic iron with 1-10] orientation is formed on ilmenite along 1-43-1] direction,(222)or(2-2-2-)plane of iron is transformed from(426-4-)or(4-2-64)plane of ilmenite firstly.The structure change during the course of reduction from ilmenite to iron is a gradually changing process. |
