Abstract: Disclosed are an apparatus and a method to synthesize powders typed diamond with the size between several tens nm to several μm in diameter using conventional CVD processes for deposition of diamond films. Gas phase nucleation has been induced on the boundary of plasmas, and as a result the spherical diamond powders accumulated have been obtained on circumferences of the normal substrate. With a modification of a substrate structure, a large area accumulation of the diamond powders of around 100 mm in diameter has been accomplished.

Abstract: A hollow diamond shell with a size of a few micrometer to hundreds of micrometer and having a geometrical shape and its fabrication method are disclosed. A diamond film is deposited by a CVD method and porous grits are used as a victim substrate to be etched later, so that the substrate can be easily removed by a capillary phenomenon that an etching solution can be intensively absorbed in a substrate etching process. Thus, a perfect diamond shell with only a plurality of fine pores with a nano size without any conspicuous opening can be obtained. Also, a diamond shell with a small opening of below 10 percent of the surface area of grits can be fabricated by controlling a nuclear generation of diamond particles.

Abstract: This invention provides a method for fabricating geometrical diamond/matrix composites where all or a part of surfaces of the matrix are covered with a diamond film, and to fabricate hollow diamond shells using the composites where a part is uncoated with a diamond film. Hollow diamond shells were prepared by etching out of the matrix soluble with chemicals through an opening, a zone on the matrix, uncoated with diamond film. By changing the shape and the size of the geometrical matrixes, various kinds of diamond/matrix composites and diamond shells in shape and in size can be fabricated. The sizes available are between 200 nm and 2 mm.
