摘要
对近年来以溶胶-凝胶法制备纳米氧化镁粉体的几种工艺进行了总结比较,并展望了该法的发展前景。溶胶-凝胶法与传统方法相比,通过液相化学途径在低温条件下制备出纯度高、粒径小、分布均匀且化学活性良好的粉体材料。最后详细介绍了目前的制备工艺中所存在的难点与不足,并指出今后的研究方向。
This paper has summarized the Sol - Gel technologies of preparation for nanometer magnesia powder in the recent years, and the development of this method was discussed in details. Compared with the traditional ways ,it can produce many kinds of nanometer powder by liquid phase, and it＇ s products have high purity,small size,uniform distribution and well chemical activity. In the end,the difficults and disadvantages in the research and the paths for the future are pointed out.
