Abstract

PURPOSE:To enable production of a high-thermal conductivity part at a relatively low cost, by providing a diamond aggregate, containing a multilayered structure having different crystal forms in which a certain layer and layers specifically adjacent thereto consist of specific grains. CONSTITUTION:This high-thermal conductivity part contains a diamond aggregate having diamond crystals of a multilayered structure in different growth forms in respective layers. Diamond grains constituting a certain layer of the multilayered structure have >=2 aspect ratio and >=100mu length of the major axis and most thereof have constant regularity in the orientation direction. Furthermore, other layers formed and laminated to the above-mentioned layer contact the end of the aforementioned orientation direction and consist of diamond grains having <=10mu respective grain diameter. In producing this aggregate, a carbon raw material of pyrolytic graphite or amorphous carbon and a catalyst of pure iron or iron alloy are laminated or concentrically and oppositely placed and reacted above the eutectic temperature of both under a pressure on the equilibrium line or above of the diamond and graphite. A film of diamond or diamond-like carbon or mixture thereof is formed on the ends of the aggregate in the orientation direction by a vapor synthetic method.
