Temperature Characteristic of TiSn-Substituted Manganese-zinc Ferrites

摘要：

In this paper, several new main compositions are presented with Mn2+ substituted by Ti4+ and Sn4+ in manganese-zinc ferrites in consideration of the strong effects of Ti4+ and Sn4+ on temperature characteristics. All samples were prepared by the conventional ceramic process. The effects of these substitutions on such parameters as permeability (μi), electrical resistivity (ρ), density (d), and power loss (Pcv) are analyzed. The experimental results show that the proper Ti4+ substitution and Sn4+ substitution in MnZnferrite can remarkably improve the magnetic properties and temperature characteristics of MnZn ferrites,especially MnZn ferrites with high thermal stability in the range of 25℃-140℃ are achieved when the substitution of Ti4+ is 0.2 mol ％ and Sn4+ is 0.1 mol ％.
