摘要:
A lithium-iron-manganese complex oxide having a layered rock-salt structure comprising a solid solution formed by dissolving lithium ferrite (LiFeO 2 ) in Li 2-x MnO 3-y (0≦x≦2, 0≦y≦1) of a layered rock-salt structure in a homogeneous crystalline state in such a way that an iron rate satisfies the relationship of 0.2≦Fe/(Fe+Mn)≦0.75, wherein at least 10% of iron contained in said solid solution is in a tetravalent state. The lithium-iron-manganese complex oxide is useful as cathode materials for a next generation low-priced lithium-ion battery and catalyst materials.

摘要:
A process for producing a sintered magnet composed of ferrite particles with magnetoplumbite structure exhibiting a large magnetic flux density and a high coercive force, at a relatively low temperature for a short period of time by filling ferrite particles with magnetoplumbite structure produced by a wet-method, in a mold; and supplying an electric current to the ferrite particles with magnetoplumbite structure filled in the mold under a pressure.
