Orientation and Growth of Grains in Copper‐Activated …

Hexagonal boron nitride powder was hot pressed in an environment of metallic copper. When compared with a copper‐free system, the sintered body exposed to the copper was composed of substantially thicker grains having an unusual arrangement, consisting of preferred alignment of (0001) basal planes parallel to the pressure axis.

Thermal Conductivity of Hot-Pressed BN Ceramics ...

Hexagonal boron nitride ceramics with sintering additives were synthesized by uniaxial hot-pressing. Hot pressing was carried out at 1800oC for 2 h under the uniaxial pressure of 30 MPa under a nitrogen atmosphere. Thermal conductivity perpendicular and parallel to the direction of the hot-pressing axis was measured by the laser-flush method.
