Document Type and Number:
Japanese Patent JP4245310
Kind Code:
B2
Abstract:
A metal plating solution comprising diamond powder dispersed and suspended therein at a concentration or rate of 0.01 to 160g per liter, wherein;
(i) said diamond powder has an element composition consisting mainly of carbon in the range of 72 to 89.5% by weight, hydrogen in the range of 0.8 to 1.5%, nitrogen in the range of 1.5 to 2.5% of, and oxygen in the range of 10.5 to 25.0%, summing those four elements up to 100% by weight or less,
(ii) and, substantially all of said particles of said diamond powder are in the range of 2 nm to 50 nm in diameters thereof (80% or more by number average, 70% or more by weight average),
(iii) and, particles of said powder exhibit a strongest peak of the intensity of the Bragg angle at 43.9° (2¸±2°), strong and characteristic peaks at 73.5° (2¸±2°) pertinent to a (220) crystal structure, a strong and characteristic peak at 95° (2¸±2°), pertinent to a (311) crystal structure, a warped halo at 17° (2¸±2°), pertinent to a graphine structure or to a benzene ring structure and no peak at 26.5°(2¸±2°) to be referred graphite (002) crystal structure, by X-ray diffraction (XRD) spectrum analysis using Cu-K± radiation,
(iv) and, the specific surface area of said powder is not smaller than 1.50x10 5 m 2 /kg, and substantially all of the surface carbon atoms of said particles are calculated being bonded with hetero atoms consisting of said hydrogen, nitrogen and oxygen, and total absorption space of said powder is 0.5m 3 /kg or more, when dried.
