    Abstract: A heat spreader including a plurality of carbonaceous particles present in an amount of at least about 50% by volume of the heat spreader. A non-carbonaceous infiltrant is also present in an amount of at least about 5% by volume of the heat spreader, the non-carbonaceous infiltrant including an element selected from the group consisting of Cu, Al and Ag. In another aspect, the carbonaceous particles may be sintered or fused directly to one another. The heat spreader can be incorporated into a cooling unit for transferring heat away from a heat source, which includes a heat sink with the heat spreader disposed in thermal communication with both the heat sink and the heat source.

    Abstract: Discontinuous diamond particulate containing metal matrix composites of high thermal conductivity and methods for producing these composites are provided. The manufacturing method includes producing a thin reaction formed and diffusion bonded functionally graded interactive SiC surface layer on diamond particles. The interactive surface converted SiC coated diamond particles are then disposed into a mold and between the particles and permitted to rapidly solidify under pressure. The surface conversion interactive SiC coating on the diamond particles achieves minimal interface thermal resistance with the metal matrix which translates into good mechanical strength and stiffness of the composites and facilitates near theoretical thermal conductivity levels to be attained in the composite. Secondary working of the diamond metal composite can be performed for producing thin sheet product.

    Abstract: A porous metal body having a foam structure of 500 nullm or less in average pore diameter, wherein the skeleton is composed of an alloy primarily including Fe and Cr, and Cr carbide or FeCr carbide is uniformly dispersed in the texture. The metal porous body is produced by preparing a slurry primarily containing an Fe oxide powder having an average particle diameter of 5 nullm or less, at least one powder selected from metallic Cr, Cr alloys, and Cr oxides, a thermosetting resin, and a diluent, applying a coating of this slurry to a resin core body having a foam structure, performing drying, and thereafter, performing firing in a non-oxidizing atmosphere so as to produce a metal porous body having the aforementioned skeleton structure.
