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+ on thermal stability by different mechanisms. Moreover, the effects of these substitutions on such parameters as permeability, electrical resistivity, density, and power loss are analyzed. The experimental results show that the proper substitution of Ti4+ or Co2+ in manganese-zinc ferrites can increase the thermal stability remarkably. Furthermore, the effects of composition of Ti4+ and Co2+substitutions have interactive process, especially when Manganese-zinc ferrites with high thermal stability in 20°C~140°C are achieved when the substitution of Ti4+ is 0.10mol%and Co2+ is 0.05mol%.
