Ternary HfB 2 ‐ZrB 2 and HfB 2 ‐HfC composites (see figure) with 20 vol.‐% MoSi 2 were produced from commercial powder and densified through pressureless sintering. Dense materials with fine microstructures were obtained at 1900–1950 °C. Flexural strength at 1500 °C confirmed the excellent stability of the composites at high temperature.
