Thermal Stability of CoTi-Substituted Manganese-zinc Ferrites

摘要：

In this paper,several new main compositions are presented with Mn2+ substituted by Ti4+and Co2+ in Manganese-zinc ferrites in consideration of the strong influence of Ti4+ and Co2+ onthermal stability by different mechanisms.Moreover,the effects of these substitutions on suchparameters as permeability,electrical resistivity,density,and power loss are analyzed.Theexperimental results show that the proper substitution of Ti4+ or Co2+ in manganese-zinc ferrites canincrease the thermal stability remarkably.Furthermore,the effects of composition of Ti4+ andCo2+substitutions have interactive process,especially when Manganese-zinc ferrites with highthermal stability in 20℃～140℃ are achieved when the substitution of Ti4+ is 0.10mol％and Co2+ is0.05mol％.
