Abstract
A method for manufacturing a sintered body, the method including heating a mixture that contains a plurality of particles of a metal oxide having a spinel-type structure, and a metal acetylacetonate under pressure at a temperature of from a melting point or higher of the metal acetylacetonate to 600° C. or lower, to form a sintered body that contains the metal oxide having the spinel-type structure.
Claims10
A structure comprising:
- a first plurality of particles of a first metal oxide having a spinel structure, the first plurality of particles of the first metal oxide having the spinel structure have an average particle size of 0.02 μm to 1 μm;
- a second plurality of particles of a second metal oxide having a spinel structure, the second plurality of particles having a smaller particle size than that of the first plurality of particles, and the second plurality of particles surrounding each of the first plurality of particles;
- and
- an amorphous phase interposed among and surrounding the first plurality of particles and the second plurality of particles such that the amorphous phase fills any space between the first plurality of particles and the second plurality of particles, the amorphous phase composed of only inorganic components and containing metal elements that are the same as at least two metal elements contained in one or both of the first metal oxide and the second metal oxide,
- wherein at least one of the first metal oxide and the second metal oxide contains at least one of Ni and Mn, and
- wherein the metal elements in the amorphous phase are at least one of Ni and Mn.
