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.
