| Abstract: | By high pressure and high temperature (HPHT) method, we used hexagonal boron nitride (hBN) as raw materials, Li3N, Li3N+LiH, LiH, LiH+LiNH2, Li3N+LiNH2 as catalyst, and successfully prepared thick plate, spherical, octahedron or hex-octahedron, flat cone and flaky hexagon morphology cubic boron nitride (cBN) crystals with relevant growth conditions. It was summarized that various Li-based catalysts/additives had distinct effects on the cBN crystal morphologies synthesized. |
| Keywords: | cubic boron nitride (cBN catalysts/additives crystal morphologies |
