In this work Mo03 was added to the Mn-Zn ferrite with the basic composition of (52mol% of Fe203, 34mol% of MnO, 14mol% of ZnO) at concentrations of 0.08, 0.5, 1 and 5 wt%. The optimum sintering condition was determined based on maximum Q factor values. The microstructure of the sintered samples was studied using SEM. The magnetic properties were characterized by determining Q factor and Curie temperature. Results showed that the addition of MoO3 increased Curie temperature and noticeably decreased linear shrinkage. The Q factor was maximized at a concentration of 0.5 wt% MoO3 making this value the best.
