Abstract

The uniform cobalt phosphate nanoparticles were successfully synthesized by microwave radiation. The effects of microwave irradiation power and reaction time on the treatment process were investigated. The products synthesized were analyzed by field emission scanning electron microscopy, X-ray powder diffraction, Fourier-transform infrared spectroscopy, thermal gravimetric analyses and dynamic light scattering. In this research, the products were cobalt phosphate phase with nanoparticles over the ranges of 60-80 nm. The data revealed that the nearly spherical particle size decreased with increasing irradiation power. The cobalt phosphate nanoparticles were formed after 10 min of microwave irradiation.

Key words: Cobalt(II) phosphate; nanoparticles; microwave radiation; X-ray diffraction.
