Abstract: By using a CBN synthesis catalyst containing a CBN synthesis catalyst component coated with an organic substance for producing cubic boron nitride (CBN), the CBN can be produced at a high transformation ration and a high yield ratio. Each of the CBN grains produced through this method has a sharp shape with a highly developed (111) plane, exhibits high strength, and exhibits a small reduction in strength due to heating. The amount of catalyst component contained in the CBN is 7.5×10−4 mol or less per 1 mol of CBN.

Abstract: Methods of synthesizing superabrasive particles such as diamonds and cubic boron nitride are disclosed and described. One procedure includes providing a superabrasive precursor including a source material in a metal matrix. The carbon source can contain a majority of carbon atoms oriented in a rhombohedral polytype configuration. A shock wave can be passed through the carbon source that is sufficient to convert the diamond to graphite. The superabrasive precursor can be formed by dissolving hexagonal carbon in a suitable molten metal or by mixing particulate components. Similarly, hexagonal boron nitride can be used in a metal matrix which is subjected to a shock wave having sufficient energy to form cubic boron nitride. The superabrasive particles produced using these methods can be provided at relatively high yields with reduced costs.

Abstract: An improved method for synthesizing superabrasive particles provides high quality industrial superabrasive particles with high yield and a narrow size distribution. The synthesis method can include forming a growth precursor of a substantially homogeneous mixture of raw material and catalyst material or layers of raw material and metal catalyst. The growth precursor can have a layer of adhesive over at least a portion thereof. A plurality of crystalline seeds can be placed in a predetermined pattern on the layer of adhesive. The growth precursor can be maintained at a temperature and pressure at which the superabrasive crystal is thermodynamically stable for a time sufficient for a desired degree of growth. Advantageously, the patterned placement of crystalline seeds and disclosed processes allow for production of various morphologies of synthetic diamonds, including octahedral and cubic diamonds, and improved growth conditions generally. As a result, the grown superabrasive particles typically have a high yield of high quality particles and a narrow distribution of particle sizes.

Abstract: A self-grown monopoly compact grit and high pressure, high temperature process for preparing the same. The high pressure, high temperature sintered/synthesized monopoly compact grit is used in various industrial tools such as saw blades, grinding wheels, cutting tools and drill bits. Further, the monopoly compact grit of the present invention is produced from a seed of a mono-crystal of diamond or cubic boron nitride surrounded by either a self-grown crystal layer or an integrally bonded poly-crystalline sintered compact layer. The self-grown crystal layer is a new grown crystal structure where the seed crystal grows into a new phase through a normal diamond or cubic boron nitride synthesis process in the presence of a catalyst metal solvent. The compact layer is composed of about 50 to about 90 volume percent of diamond or cubic boron nitride, a typical binder material, which is a catalyst for crystal-to-crystal bonding, and a cementing agent which is a binding agent capable of forming stable carbide and nitride bonds.

Abstract: A cell for forming a composite hard material and hard materials and methods of forming composite hard materials. A cell (10) in which the article is formed includes a talc outer sleeve (12), a glass sleeve (14) and a reflecting foil (22). A heater (18) is arranged inwardly of the foil (22) and a barrier layer (16) is arranged inwardly of the glass sleeve (14). A central column (20) is defined for receiving the charge of material (50) from which the hard composite material is to be formed. The charge material is located in a mold (76, 100) which can define the final shape of the article thereby avoiding the need for additional machining, and the mold and charge material are subject to high temperature and pressure to form the composite material while maintaining the charge subject to hydrostatic pressure during the application of pressure and high temperature and maintaining a low temperature gradient across the charge during formation of the composite hard material to reduce uneven pressurization of the composite hard material. The article may also be formed by forming first and second mixtures (120, 130) of composite hard material so as to form an outer surface on the article which has a higher hard particle content than an interior core portion of the article.
