    IPC: C04B35/26

    Abstract: The sintered ferrite at a low temperature is prepared by mixing and heat-treating Bi2O3 and other oxides to calcined ferrite powder; and adding a liquid forming agent to form a stable phase. Bi2O3 of the liquid forming aid agent and other oxides are mixed to give a composition such that the liquid phase temperature in the phase diagram is in the range of 750 to 850 deg.C. The ferrite can be used for a noise filter and inductor.
