    摘要: A diamond or cubic boron nitride crystal containing growth discontinuities resulting from changes in the environment of the growing crystal and having at least one smooth outside surface which intersects the growth discontinuities is charged electrostatically, a fine powder is applied to the charged smooth surface and the applied powder produces a pattern on the charged surface which is a delineation of the intersected growth discontinuities.

    摘要: A smooth surface of a diamond or cubic boron nitride crystal is bombarded with ions sufficiently to penetrate the surface and impart an ion implanted region in the crystal in a predetermined pattern, the resulting crystal is charged electrostatically, and a powder is applied to the charged smooth surface producing a pattern thereon which is a delineation of the implanted region and can be used to identify or fingerprint the crystal.

    摘要: Improvements are provided in reaction vessel construction used in the growth of diamond by the process disclosed in U.S. Pat. No. 3,297,407 -- Wentorf, Jr. In assembly of the reaction vessel of this invention, the plug of catalyst-solvent material is disposed between the source of carbon and the diamond seed material as in the Wentorf, Jr. patent and, in addition, the diamond seed material is separated from the catalyst-solvent plug by means for isolating the diamond seed material from the catalyst-solvent material until after the latter has become saturated with carbon from the source of carbon. In addition, preferably the under surface of the plug of catalyst-solvent metal is covered with means for suppressing diamond nucleation. The nucleation suppressing means is usually in the form of a disc and may completely cover the underside of the catalyst-solvent plug or may have a hole therethrough in juxtaposition to the diamond seed/isolating means combination(s). When both the isolating means and the nucleation suppressing means are employed, capability is provided for simultaneously preventing dissolution of the diamond seed and suppressing spurious diamond nucleation.
