Additions of V2O5 were used to decrease the sintering temperature and to enhance the densification of NiZnCu ferrite. With a small amount of V2O5 (0.6–1.2 wt%) as a sintering aid, densification at low sintering temperature was observed. EDS analyses showed the presence of vanadium inside the ferrite grains. Microstructure investigation revealed heterogeneous grain size...
