· Ti2 Ni1 Se4

Ti2Ni1Se4 is an intermetallic semiconductor compound combining titanium, nickel, and selenium in a fixed stoichiometric ratio. This material belongs to the broader family of transition-metal chalcogenides and is primarily of research interest rather than established in high-volume industrial production. The compound is investigated for potential applications in thermoelectric devices, optoelectronics, and solid-state energy conversion where its semiconducting properties and mechanical stiffness could enable efficient heat-to-electricity or light-sensing performance at moderate temperatures.

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.
