The authors discuss pressureless sintering of hexagonal boron nitride (BN) performed using a powder activated by mechano-chemical treatments. Physical properties of the sintered BN bodies depend on the type of starting powder and the conditions of the treatments. The BN body, which was obtained at 2000{sup 0}C using an appropriate activated powder, was 99 wt% pure and was excellent in mechanical and physical properties, in spite of its low density.
