A method for producing a powder for magnetic ferrite

A method including mixing powders of at least one of MgO, Mg(OH)2, and MgCO3, and powders of Fe2O3, CuO and ZnO, pre-sintering the mixed powder at 900° or lower, milling the pre-sintered raw powder, pressing the milled powder to form a pressed body and sintering the pressed body to form a magnetic f...

Summary:A method including mixing powders of at least one of MgO, Mg(OH)2, and MgCO3, and powders of Fe2O3, CuO and ZnO, pre-sintering the mixed powder at 900° or lower, milling the pre-sintered raw powder, pressing the milled powder to form a pressed body and sintering the pressed body to form a magnetic ferrite powder such as MgCuZn, MgNiCuZn, or NiCuZn.
