摘要 以金属铋、氢氧化钠为原料,采用二步法合成了超细氧化铋粉体。利用激光粒度分析仪、扫描电镜分析、化学分析法、热重-差示扫描量热法等对氧化铋进行了表征,分析结果表明:采用二步法制备氧化铋粉体颗粒均匀、呈球形、分散性好,平均粒径0.2μm。 Using Bi and NaOH as starting material, Bi2O3 powder was prepared by two-step method. Bi2O3 powder was determined by size meter, SEM, TG/DSC and chemical analysis. The results show that Bi2O3 powder prepared by two-step method were grain uniformity, spherical powder, disperse fine and the average size is 0.2 μm .
