摘要
利用激光粒度分析仪和电子探针扫描仪检测了粗颗粒三氧化钨还原和氧化的粒度分布。通过2次还原和2次氧化可以制备出粒度分布在0．11μm与0．55μm之间占98．08％,比表面积(BET)为3．471 m2／g的亚微米三氧化钨。
With the laser particle size distribution measuring instrument and the electron probe scan instrument, the particle size distribution and the SEM of WO3 reduction-reoxidation were tested. The results show that submicron WO3 can be prepared with coarse WO3 through circulatory reduction and oxidation twice. The percentage of the particle size distribution between 0.11 μm and 0.55 μm is 98.08% in submicron WO3, and the BET of it is 3.471 m^2/g.
