Investigation of the Mechanism of Polycondensation Synthesis of Molybdenum Trioxide under Solvothermal Conditions Using the Method of Dynamic Light Scattering
Abstract
The processes of formation and dispersion of monoclinic and hexagonal molybdenum trioxide phases during the course of thermoinduced polycondensation of molybdic acid in aqueous medium at 100 °C were investigated with the use of dynamic light scattering technique. It has been shown that programmed changing of the concentration of the reaction medium makes it possible to exert an effective control over the nucleation and particle growing in the solution and permits one to obtain perfect prismatic crystallites of metastable hexagonal molybdenum trioxide with the medium size from 200–500 nm to 10 μm.
