Nb5Si3B
metal· JVASP-62107· Nb5Si3B
Nb5Si3B is an experimental intermetallic compound combining niobium, silicon, and boron, belonging to the family of advanced refractory metal silicides being developed for ultra-high-temperature structural applications. This material is primarily of research interest for aerospace and power generation sectors seeking to extend operating temperatures beyond conventional superalloys, with potential applications in engine hot sections and thermal protection systems where its refractory character and low density relative to density-normalized strength offer advantages over nickel-based alternatives.
