GE Advanced Ceramics boron nitride (BN) powders of grades HCP, HCPH, HCPL, and AC6004 are generally single-crystal hexagonal platelets with very high purity. The mean particle sizes for these ultra-fine powders are in the range of 6 to 13 µm, and they are >99.9% -325 mesh. HCPH is processed to consist of a more agglomerated structure than HCP, and therefore a higher specific surface area. This makes it ideal for creating good particle-to-particle contact in a matrix.
