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