Abstract
A brief historical review of research concerning super-hard materials in the boron suboxide system is described with an emphasis on the synthesis and sintering of hexaboronoxide (B6O). Authors' investigations of the preparation of B6O-based super-hard materials are also described along with the formation behavior of B6O powder in a high temperature reaction between amorphous boron and B2O3. The structure and properties of the single phase B6O sintered compact obtained under high pressure are discussed in reference to the literature. The sintered composites in the B6O-B4C and B6O-cBN systems were prepared under high pressure and temperature conditions (3-6 GPa, 1500-1800Åé). The mechanical properties (hardness and toughness) and chemical stability are related to the phase relationship in the above quasi-two component systems and the microstructures of sintered composites.
