Abstract: The present invention relates to a gold powder comprising gold having a purity of 99.9% by mass or more and having an average particle size of 0.01 µm or more and 1.0 µm or less. In this gold powder, a content of a chloride ion is 100 ppm or less, and a content of a cyanide ion is 10 ppm or more and 1000 ppm or less. A total of the content of a chloride ion and the content of a cyanide ion is preferably 110 ppm or more and 1000 ppm or less. The gold powder of the present invention is excellent in adaptability to various processes including bonding or the like with a content of a chloride ion, that is, an impurity, optimized. A gold paste using this gold powder is suitably used in various uses for bonding such as die bonding of a semiconductor chip, sealing a semiconductor package, and forming an electrode/wire.

Abstract: A powder magnetic core containing a magnetic particle of an Fe-based Cr-containing amorphous alloy and an organic binding substance is provided as a powder magnetic core with a small loss and high initial permeability. When the depth profile of the composition is determined from the surface of the magnetic particle in the powder magnetic core, the depth profile has the following characteristics.
(1) An oxygen-containing region with an O/Fe ratio of 0.1 or more can be defined from the surface of the magnetic particle, and the oxygen-containing region has a depth of 35 nm or less from the surface of the magnetic particle.
(2) A carbon-containing region with a C/O ratio of 1 or more can be defined from the surface of the magnetic particle, and the carbon-containing region has a depth of 5 nm or less from the surface of the magnetic particle.
(3) The oxygen-containing region has a Cr-concentrated portion with a bulk Cr ratio of more than 1.
