AbstractCaB(2)O(4) was added into hexagonal boron nitride (hBN) to improve the sintering behaviors of hBN. CaB(2)O(4) and hBN were mixed and then pressed into plates. The plates were sintered at 2000 degrees C for 5h under a N(2) ambience. The phase compositions with different CaB(2)O(4) contents were examined with X-ray diffraction analysis. The fracture cross-sections of the hBN plates were investigated by SEM. The apparent density and Rockwell hardness were also measured. The results show that the hBN particles had a plate-like shape and the grain sizes of liBN increased with increasing CaB(2)O(4) contents. The apparent density and Rockwell hardness decreased with increasing CaB(2)O(4) contents. When the CaB(2)O(4) content was 15(wt) %, the hBN has the average grain sizes of 3 mu m in diameter and 200nm in thickness, the apparent density of 1.06 g/cm(3) and the Rockwell hardness of 3, respectively.
