Pure polycrystalline MnTeMoO₆ is highly desirable to crystal growth. Polycrystalline MnTeMoO₆ has been synthesized by solid-state reaction techniques. The optimized preparation process, phase purity and reaction mechanism of polycrystalline MnTeMoO₆ were investigated. The reaction will be paused if the atoms cannot pass through the grain boundary and restarted after ground intimately. A new method combined with X-ray diffraction and microscopic observation is employed to determine the phase purity of polycrystalline MnTeMoO₆. Pure polycrystalline MnTeMoO₆ with gray color and single crystalline phase can be obtained after the reactant was calcined at 500 °C for 20 h three times and can be used to crystal growth. This method for determining the phase purity of powder sample can be used in the synthesis of other polycrystalline powders.
