Ti4 Si4

Ti4Si4 is a titanium silicide compound that belongs to the family of refractory intermetallic materials, combining titanium and silicon in a defined stoichiometric ratio. This material is primarily of research and developmental interest for high-temperature structural applications where lightweight performance and thermal stability are critical, particularly in aerospace and power generation sectors seeking alternatives to superalloys. Ti-Si compounds are notable for their potential to operate at elevated temperatures while maintaining lower density than conventional nickel-based superalloys, though they typically face challenges with oxidation resistance and room-temperature brittleness that limit current commercial adoption.
