摘要

采用动态光散射法研究了 100°C 水介质中钼酸的热诱导缩聚过程中单斜和六方三氧化钼相的形成和分散过程。通过程序改变反应介质的浓度，可以有效控制溶液中颗粒的成核和生长。可以获得平均尺寸从 200-500 nm 到 10 μm 的右棱柱形可转移六方三氧化钼晶体。

Investigation of the Mechanism of Polycondensation Synthesis of Molybdenum Trioxide Under Solvothermal Conditions Using Dynamic Light Scattering

Formation and dispersion processes of monoclinic and hexagonal molybdenum-trioxide phases during thermally induced polycondensation of molybdic acid in aqueous medium at 100°C were investigated using dynamic light scattering. Programmed variation of the reaction medium concentration made it possible to control effectively particle nucleation and growth in the solution. Right prismatic crystallites of metastable hexagonal molybdenum trioxide with an average size from 200–500 nm to 10 μm could be obtained.
