摘　　要：本文针对稀土二钼酸铵与二钼酸铵的形貌、成分、松装密度、费氏粒度、粒度分布和热分解特性进行了研究对比,结果表明,稀土二钼酸铵同二钼酸铵一样为晶界清晰的非团聚态晶体,两者的钼含量接近,且稀土二钼酸铵和二钼酸铵热重分析图谱接近一致;稀土二钼酸铵是NH4La(Mo O4)2和二钼酸铵的均匀混合物。Themorphology,composition,apparent density,Fisher particle size,particle size distribution,and thermal decomposition characteristics of rare earth ammonium dimolybdate and ammonium dimolybdate were investigated in this paper. The results show that both of rare earth ammonium dimolybdate and ammonium dimolybdate were non-agglomeration state crystals with clear boundaries. The molybdenum contents of rare earth ammonium dimolybdate and ammonium dimolybdate were close and they share the very close thermogravimetry spectra.
