· JVASP-54300· TiAs2

TiAs₂ is an intermetallic compound combining titanium and arsenic, belonging to the family of transition metal arsenides. This material is primarily of research and specialized industrial interest rather than a mainstream engineering material, with potential applications in high-temperature electronics, thermoelectric devices, and semiconductor contexts where arsenic-containing intermetallics may offer unique electronic or thermal properties. Engineers would consider TiAs₂ in niche applications requiring materials that operate at elevated temperatures or possess specific electrical characteristics unavailable in conventional titanium alloys, though its use remains limited compared to established Ti-based alloys due to manufacturing complexity, arsenic toxicity considerations, and processing challenges.

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.
