摘　　要：以BaCl_2、TiCl_4为原料,以(NH_4)_2C_2O_4·H_2O为沉淀剂,利用微波-沉淀法制备了高纯四方相钛酸钡纳米粉体。应用XRD、TEM等对粉体的结构、形貌进行了分析。研究表明,微波-沉淀法合成粉体的时间为50 min,制备的粉体属于四方相晶体结构,粒度为30nm、粒度分布均匀,杂质含量达到电子行业工业标准。Through the microwave-precipitation process, the super-pure nanopowders barium titanate were prepared by using titanium tetrachloride and barium chloride H2O as the precipitant and alcohol as dispersant. The particle size, discussed using XRD and TEM. The experimental results show precipitation process have higher purity, finer particle （size is 30 but the synthesization time of powders is only 50min. as raw materials and （ NH4）2C2O4· crystal phase and figure were detailed that the powders by the microwavenm）, more uniform size distribution,but the synthesization time of powders is only 50min.
