· 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.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
