摘要： A reduction treatment agent made of a powder with a particle size within a range of 1500 to 3000 mesh, the powder containing: 20 to 40 parts of a mixed-oxide powder containing magnesium oxide and zinc oxide; and 60 to 80 parts of an organic acid powder containing calcium, ascorbic acid, citric acid and salt. The reduction treatment agent may further contain one to six kinds of metal powder selected from the group of copper, molybdenum, nickel, cobalt, iron and aluminum, each in an amount of one part. Due to this configuration, the reduction treatment agent can be easily mixed with various substances when added to those substances. Even if the target substance is not water, the agent can entirely and uniformly change that substance into a reduced state. Additionally, the reduction treatment agent can act as a surfactant, and therefore, can be used as cosmetics or food.

摘要： There are provided a permanent magnet and a manufacturing method thereof enabling, even when wet milling is employed, carbon content contained in magnet particles to be reduced in advance before sintering, and also enabling the entirety of the magnet to be densely sintered without causing a gap between a main phase and a grain boundary phase in the sintered magnet. Coarsely-milled magnet powder is further milled by a bead mill in an organic solvent. Thereafter, the magnet powder is compacted to produce a formed body. Hydrogen calcination process is performed through holding the formed body for several hours in hydrogen atmosphere at a pressure higher than normal atmospheric pressure at 200 through 900 degrees Celsius. Thereafter, through sintering process, a permanent magnet 1 is manufactured.

摘要： A sintered magnet body (RaT1bMcBd) coated with a powder mixture of an intermetallic compound (R1iM1j, R1xT2yM1z, R1iM1jHk), alloy (M1dM2e) or metal (M1) powder and a rare earth (R2) oxide is diffusion treated. The R2 oxide is partially reduced during the diffusion treatment, so a significant amount of R2 can be introduced near interfaces of primary phase grains within the magnet through the passages in the form of grain boundaries. The coercive force is increased while minimizing a decline of remanence.
