摘　　要：采用化学沉淀法,较好地将电气石粉体与活性ZnO进行表面包覆,其中ZnO的平均粒径为78.71nm,达到亚微米级,复合粉体的电阻率降低,导电性能提高,为进一步拓宽电气石粉体在环境净化领域的应用奠定了基础。Sub-micron-scale zinc oxide/tourmaline powders were prepared by the chemical deposition method, the average particle size of zinc oxide is 78.71 am, which belongs to sub-micron-scale .The ratio of resistance of the powders was reduced and the capability of electric conduction was advanced. The research established the foundation which the tourmaline powders would be farther exploited in environment decontaminate.
