Abstract
- Textured hexagonal boron nitride (BN) composite ceramics with mullite as sintered additive were fabricated by hot-press sintering under different pressures. The degrees of texture and the microstructures of these materials were evaluated using X-ray diffraction, pole figures and scanning electron microscopy. The results showed that the hexagonal BN composite ceramics have obvious directional orientation. The preferred orientation of the c-axis of hexagonal BN grains was along the direction of pressure, and the sintering pressure influences texture formation. [ABSTRACT FROM AUTHOR]
