Abstract: The present invention provides methods of forming high quality diamond bodies under high pressure, and the diamond bodies produced by such methods. In one aspect, a method is provided for growing a diamond body, including providing a non-particulate silicon carbide (SiC) mass having a pre-designed shape, placing the SiC mass under high pressure in association with a molten catalyst and a carbon source, and maintaining the SiC mass under high pressure to form a substantially monocrystalline diamond body. The diamond body may be formed across substantially all of the SiC mass having surface area exposed to the molten catalyst. As such, the diamond body may conform to the shape of the exposed surface area of the SiC mass.

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: High pressure synthesis of various crystals such as diamond, cBN and the like can be carried out using reaction assemblies suitable for use in methods such as temperature gradient methods. The reaction assembly can be oriented substantially perpendicular to gravity during application of high pressure. Orienting the reaction assembly in this manner can avoid detrimental effects of gravity on the molten catalyst, e.g., convection, hence increasing available volumes for growing high quality crystals. Multiple reaction assemblies can be oriented in series or parallel, each reaction assembly having one or more growth cells suitable for growth of high quality crystals. Additionally, various high pressure apparatuses can be used. A split die design allows for particularly effective results and control of temperature and growth conditions for individual crystals.

Abstract: A diamond composite heat spreader having a low thermal mismatch stress can improve reliability and cost of diamond-based heat spreaders. A diamond composite heat spreader can have a diamond film and a thermally conductive base having a residual thermal mismatch stress which is less than about 75% of a residual thermal mismatch stress which would result from forming the diamond film on the thermally conductive base using a high temperature deposition process at 700° C. The diamond film can be formed on the thermally conductive base using a low temperature vapor deposition process.

Abstract: Diamond heat spreaders are produced having thermal properties approaching that of pure diamond. Diamond particles of relatively large grain size are tightly packed to maximize diamond-to-diamond contact. Subsequently, smaller diamond particles may be introduced into the interstitial voids to further increase the diamond content per volume. An interstitial material is then introduced which substantially fills the remaining voids and should have favorable thermal properties as well as form chemical bonds with the diamond. Alternatively, the packed diamond may be subjected to ultrahigh pressures over 4 GPa in the presence of a sintering aid. The resulting diamond heat spreader has diamond particles which are substantially sintered together to form a continuous diamond network and small amounts of a sintering agent. The final heat spreader exhibits superior heat transfer properties advantageous in removing heat from various sources such as electronic devices and minimized difference in thermal expansion from the heat source.
