摘要: A silver brazing material containing silver, copper, zinc, manganese, nickel, and tin as indispensable constituent elements. The silver brazing material includes 35 mass % or more and 45 mass % or less silver, 18 mass % or more and 28 mass % or less zinc, 2 mass % or more and 6 mass % or less manganese, 1.5 mass % or more and 6 mass % or less nickel, and 0.5 mass % or more and 5 mass % or less tin, with the balance being copper impurities. Within these compositional ranges, a predetermined relation is set between the manganese content and the nickel content, whereby the silver brazing material can be provided with excellent characteristics also in terms of processability or wettability. In the silver brazing material of the present invention, the silver content is reduced, and also melting point reduction and the narrowing of the temperature difference between solidus temperature and liquidus temperature are attempted.

摘要: 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, 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 has improved 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.

摘要: Provided is a perpendicular magnetic recording medium that exhibits improved thermal stability and achieves reduction in switching magnetic field by providing a cap layer having characteristics (characteristics contributing to reducing switching magnetic field of the perpendicular magnetic recording medium as well as to improving thermal stability thereof) superior to existing cap layers.
A perpendicular magnetic recording layer (24) has a granular structure which comprises Co- Pt-alloy magnetic crystal grains (24A) and a non-magnetic grain boundary oxide (24B). A cap layer (26) has a granular structure which comprises Co-Pt-alloy magnetic crystal grains (26A) and a magnetic grain boundary oxide (26B). The Co- Pt -alloy magnetic crystal grains (26A) in the cap layer (26) contain 65-90 at % of Co and 10-35 at % of Pt. The magnetic grain boundary oxide (26B) is included in a volume fraction of 5-40 vol % with respect to the total volume of the cap layer (26).-

摘要: A sealing structure including: a set of base members forming a sealed space; a through-hole which is formed in at least one of the base members, and communicates with the sealed space; and a sealing member that seals the through-hole. An underlying metal film including a bulk-like metal such as gold is provided on a surface of the base member provided with the through-hole. The sealing member seals the through-hole while being bonded to the underlying metal film, and includes: a sealing material which is bonded to the underlying metal film, and includes a compressed product of a metal powder of gold or the like, the metal powder having a purity of 99.9% by mass or more; and a lid-like metal film which is bonded to the sealing material, and includes a bulk-like metal such as gold. Further, the sealing material includes: an outer periphery-side densified region being in contact with an underlying metal film; and a center-side porous region being in contact with the through-hole. The densified region has a porosity of 10% or less in terms of an area ratio at any cross-section.
