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： A probe pin material including a Ag—Pd—Cu-based alloy essentially including Ag, Pd and Cu, B as a first additive element, and at least any element of Zn, Bi and Sn, as a second additive element. A concentration of the first additive element is 0.1 mass % or more and 1.5 mass % or less, and a concentration of the second additive element is 0.1 mass % or more and 1.0 mass % or less. A Ag concentration, a Pd concentration and a Cu concentration in the Ag—Pd—Cu-based alloy are required as follows: a Ag concentration (SAg), a Pd concentration (SPd) and a Cu concentration (SCu) converted as given that a Ag—Pd—Cu ternary alloy is formed from only such three elements all fall within a predetermined range in a Ag—Pd—Cu ternary system phase diagram. The probe pin material is excellent in resistance value and hardness/wear resistance, and also is enhanced in bending resistance.

摘要： The present invention relates to a medical Pt—W alloy, containing 10 mass % or more and 15 mass % or less of W, with the balance being Pt and inevitable impurities, in which a Zr content is 1000 ppm or less. Limiting the Zr content can improve workability, particularly workability at the stage of hot working. Regarding impurity control, further limiting a Ca content to 250 ppm or less can provide more suitable workability. The present invention is good in workability in processing into a wire included in an embolic coil, a guide wire or the like.

摘要： The present invention relates to a medical Au-Pt-Pd alloy including Au, Pt,Pd, and inevitable impurities. The Au-Pt-Pd alloy has an alloy compositioninside a polygon (A1-A2-A3-A4) surrounded by straight lines connected at pointA1 (Au: 53 atom%, Pt: 4 atom%, and Pd: 43 atom%), point A2 (Au: 70 atom%,Pt: 4 atom%, and Pd: 26 atom%), point A3 (Au: 69.9 atom%, Pt: 30 atom%, and Pd: 0.1 atom%), and point A4 (Au: 49.9 atom%, Pt: 50 atom%, and Pd: 0.1 atom%) in a Au-Pt-Pd ternary state diagram. In a metal structure of the alloy, at least one of a Au-rich phase and a Pt-rich phase is distributed, and the total of the area ratio of the Au-rich phase and the area ratio of the Pt-rich phase is 1.5% or more and 25.4% or less.

摘要： Provided is an Fe—Pt—BN-based sputtering target that has a high relative density and that suppresses particle generation.
The Fe—Pt—BN-based sputtering target has, as a residue after dissolution in aqua regia measured by a procedure below, the particle size distribution in which D90 is 5.5 μm or less and a proportion of fine particles smaller than 1 μm is 35% or less. The procedure includes: (1) cutting out an about 4 mm-square sample piece from the sputtering target, followed by pulverizing to prepare a pulverized product; (2) classifying the pulverized product using sieves of 106 μm and 300 μm in opening size and collecting a powder that has passed through the 300 μm sieve and remained on the 106 μm sieve; (3) immersing the powder in aqua regia heated to 200° C. to prepare a residue-containing solution in which the powder has been dissolved; (4) filtering the residue-containing solution through a 5A filter paper specified in JIS P 3801 and drying a residue on the filter paper at 80° C. to prepare a residue powder; (5) dispersing the residue powder in water containing a surfactant to prepare a sample solution; and (6) setting the sample solution in a particle size analyzer and measuring the particle size distribution.-

摘要： A problem of particle generation in an Fe-Pt-BN-based sputtering target having a high relative density is resolved by an approach different from conventional methods.
An Fe-Pt-BN-based sputtering target having a relative density of 90% or more and a Vickers hardness of 150 or less can reduce the number of particles generated during magnetron sputtering.-
