【Abstract】 MnZn ferrite with low power loss and high B_s at high operating temperature has been prepared by choosing highly pure raw materials, using conventional ceramic process,and adding optimum contents of CaCO₃, TiO₂, Nb₂O₅, and V₂O₅. According to the solid-phase reaction mechanism of ferrite,optimum sintering process and matched atmosphere were used to prepare high quality MnZn ferrite material. High density, high T_c and high B_s were achieved.更多还原
