China unveils advanced ultra-high-temperature ceramics for reactors and hypersonic jets
Researchers from Harbin University highlight a two-step in-situ reactive spark plasma sintering process blending ZrC with TiSi2 and B4C to produce a multi-phase ultra-high-temperature ceramic (ZTS-30B) with nano-SiC and TiB2 reinforcements, delivering 824 MPa flexural strength and 7.5 MPa·m1/2 fracture toughness to improve densification and toughness for potential use in nuclear reactors and hypersonic propulsion.
