Abstract: Using the sol–gel process, a composite powder of HfB2–(SiO2–C) composition was synthesized and then utilized for reactive sintering (hot pressing, 30 MPa; 1800 °C, 15 min) of ultra-high-temperature ceramic HfB2–30 vol% SiC composites. It was established that nanocrystalline silicon… read more here.
