| 摘 要： | 以非晶质菱镁矿为原料通过控制煅烧温度、保温时间、升温速率得到活性氧化镁,采用柠檬酸法测定其活性,讨论了煅烧温度、保温时间和升温速率对氧化镁活性的影响,并测定了氧化镁的比表面积和分解率。结果表明,在700℃以10℃/min的升温速率保温1.5 h菱镁矿的分解率最高,所得氧化镁活性最好。

| Abstract: | The nanoparticles of avtive magnesia were prepared by controlling calcining temperature,soaking time and the heating rate using non-crystal magnesite as raw material.Their activity was measured by the citrate route.The influence factors,such as calcining temperature,soaking time and the heating rate were studied in this paper,the ratio surface of the magnesia and the rate of dissociation of the raw material has been determined as well.It was found that high active magnesia with high rate of dissociation of ... |
