Title: METHOD FOR PRODUCING Mn-Zn FERRITE
Inventor: MORIKAWA KEIICHI
IPC: C04B35/38
Filed: 2001-10-03
Abstract: PROBLEM TO BE SOLVED: To provide a means for producing ferrite which has excellent characteristics. SOLUTION: Raw material powder of 100 pts.wt. essentially consisting of Fe2 O3 , Mn3 O4 and ZnO is mixed with a reducing agent of 1.2 to 1.6 pts.wt., and this mixture is subjected to temporary burning. After that, the temporarily burned material is pulverized, and a binder or a dispersant is added thereto, and after forming, normal burning is performed thereto. By the temporary burning with the reducing agent mixed therewith, excess oxygen in the raw material is positively exhausted by the reduction action of the reducing agent to promote to make the temporarily burned material have a spinel structure, so that, even when the temporary burning is performed at a relatively low temperature, the temporarily burned material having a high spinel structure rate can be obtained.  Since the temporary burning is performed at the relatively low temperature, the growth of the crystal grains is suppressed, so that the temporarily burned material having a small grain diameter can be obtained. By subjecting the temporarily burned material to normal burning, the Mn-Zn ferrite having a spinel structure rate of 100%, having a small mean crystal grain diameter, and having excellent high-frequency properties can be obtained.
