用共沉淀法合成了单相的BaZr4(PO4)6粉体，研究了两种不同的分散方法制得的BZP粉体的粒度分布及其烧结体的力学性能。结果表明：与用有机高分子分散剂PEG改性处理相比较，采用低分子有机溶剂分散处理所制得的BZP粉体具有较窄的粒度分布，平均粒径1.6μm～1.8μm，在同样的烧结条件下，烧结体的抗压强度也明显优于前者。另外，在液相反应中控制pH=7～11，可有效防止反过程中团聚体的形成。

The single phase BZP powder was synthesized by coprecipitatemethod. The size distribution and the sinter characteristic of the powders abtained by two different dispersion methods were investigated.The results show that a narrow size distribution can be abtained by dispersing of small molecular organic solvent,and the average particle size of powder is 1.6 μm～1.8 μm. In addition,agglomeration can be prevented by controlling pH=7～11 during liquid synthesis.
