a cubic boron nitride (cBN) grain having a single crystal structure; and
a plurality of particles included within the cBN grain, wherein the plurality of particles comprise a non-catalyst material.
2. The superabrasive material of claim 1 , wherein the plurality of particles are non-binder materials.
3. The superabrasive material of claim 1 , wherein the plurality of particles comprise at least one of a metal, a metal alloy, an intermetallic compound, and a ceramic.
4. The superabrasive material of claim 1 , wherein the plurality of particles comprise at least one of a carbide, a nitride, and an oxide.
5. The superabrasive material of claim 1 , wherein the plurality of particles comprise at least one of tungsten carbide, silica carbide, boron carbide, and aluminum oxide.
6. The superabrasive material of claim 1 , wherein the plurality of particles comprise particle sizes ranging from about 10 nm to about 10 μm.
7. The superabrasive material of claim 1 , wherein the plurality of particles are separated from each other at a range from about 1 um to about 50 μm.
8. The superabrasive material of claim 1 , wherein the plurality of particles are homogeneously dispersed within the superabrasive crystal.
9. The superabrasive material of claim 1 , wherein the superabrasive crystal is substantially faceted.
10. The superabrasive material of claim 9 further comprises a plurality of pits on a facet of the superabrasive crystal.
11. The superabrasive material of claim 10 , wherein the plurality of pits have depths ranging from about 10 nm to about 30 μm.
12. A method, comprising:
providing a plurality of hexagonal boron nitride (hBN) grains;
providing a catalyst and a plurality of particles as non-binder materials; and
subjecting the plurality of hBN grains, the catalyst, and non-binder material to a high pressure and high temperature for a time period sufficient to form a single crystal structure of a cubic boron nitride (cBN) grain, wherein the plurality of particles are dispersed within the single crystal structure of the cBN grains.
13. The method of claim 12 , further comprising cleaning products by using at least one of water, acidic solutions and caustic chemicals.
14. The method of claim 12 , wherein the non-binder material comprises at least one of a metal, a metal alloy, an intermetallic compound, and a ceramic compound.
15. The method of claim 12 , wherein the non-binder material comprises at least one of a carbide, a nitride, and an oxide.
