Abstract: A method for producing a Fe—Co alloy powder suitable for an antenna includes steps, wherein when introducing an oxidizing agent into an aqueous solution containing Fe ions and Co ions to generate crystal nuclei and cause precipitation and growth of a precursor having Fe and Co as components, Co in an amount corresponding to 40% or more of the total amount of Co used for the precipitation reaction is added to the aqueous solution at a time after the start of the crystal nuclei generation and before the end of the precipitation reaction to obtain the precursor. Then, a dried product of the precursor is reduced to obtain a Fe—Co alloy powder. This Fe—Co alloy powder has a mean particle size of 100 nm or less, a coercive force Hc of 52.0 to 78.0 kA/m, and a saturation magnetization ss of 160 Am2/kg or higher.

Abstract: This invention provides a method for manufacturing parts with a built-in channel. Two kinds of materials with different melting points are used, the material with the lower melting point is a molding element with an arbitrary shape, the material with the higher melting point is powdered, and the material with the low melting point is wrapped and positioned in the powder with the high melting point. When the preparation is completed, the low-temperature material is melted down, and the channel with the random shape is formed after sintering. In the application that the metal parts need supply water, air, or oil, instead of the channel acquired by mechanical splicing or the channel molded by 3D printing technology, this method in the invention is with a wide application range, the lower cost, and the simple and controllable technology, and is suitable for mass production and with very broad market prospects.

Abstract: Provided are a rare earth permanent magnet whose permanent magnetic properties are improved by making density of the magnet very high and a method for manufacturing a rare earth permanent magnet. Thus, magnet raw material is milled into magnet powder, and then a compound is formed by mixing the magnet powder thus milled with a binder. Next, the compound thus formed is subjected to hot-melt molding onto a supporting substrate so as to form a green sheet molded to a sheet-like shape. Thereafter, while the green sheet thus molded is softened by heating, magnetic field orientation is carried out by applying a magnetic field to the green sheet thus heated; and further, the green sheet having been subjected to the magnetic field orientation is calcined in non-oxidizing atmosphere, and then, sintering thereof is carried out at a sintering temperature to produce a permanent magnet having density of 95% or more.

Abstract: An electrode for the use of an advanced lithium battery is fabricated using three-dimensionally structured metal foam coated with an active material. The metal foam is porous metal foam that can be used as an anode current collector of a lithium-ion battery and is coated with an anode active material, such as tin, through a sonication-assisted electroless plating method. Additionally, the coated metal foam is heat-treated at an appropriate temperature in order to improve the integrity of the coating layer and hence, the cyclic performance of the lithium-ion battery.
