Ti5Si4
metal· Ti5Si4
Ti5Si4 is an intermetallic compound in the titanium-silicon system, representing a ceramic-like phase that combines metallic titanium with silicon to create a hard, refractory material. This compound belongs to the family of titanium silicides, which are of significant research and development interest for high-temperature structural applications where conventional titanium alloys reach their limits. Ti5Si4 is explored primarily in aerospace and power generation contexts where elevated-temperature strength and oxidation resistance are critical, though it remains largely in the advanced materials and research phase rather than widespread production use.
