Synthesis of spinel МgМn2О4 nanoparticles by the co-precipitation method in an ultrasonic field

Nanoparticles of spinel MgMn2O4 were synthesized using the co-precipitation method in an ultrasonic field. It was established that at a calcination temperature of 200 °C, all peaks on the diffractogram of the synthesized material corresponded to spinel MgMn2O4 with a cubic lattice, pronounced crystallinity, and the absence of other phases. As the calcination temperature increased, the formation of new phases – Mn oxides (respectively, Mn5O8 and Mn2O3) – was recorded.
