Preparation and Characterization of CaMoO4 by Solid-State Microwave Metathetic Route

Abstract

A solid-state metathetic (SSM) route assisted by microwave irradiation was used to synthesize the CaMoO₄ particles in 10 min under environmentally friendly conditions. Well crystallized CaMoO₄ particles were formed at 600 ºC for 3 h, showing a fine and homogeneous morphology with sizes of 1-3 μm. The synthesized CaMoO₄ particles were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy. The optical properties were examined by photoluminescence emission and Raman spectroscopy.
