· Tm4 Ni2 As4

Tm₄Ni₂As₄ is a ternary intermetallic semiconductor compound combining thulium (a rare-earth element), nickel, and arsenic in a stoichiometric crystal structure. This material belongs to the rare-earth pnictide family and is primarily of research interest rather than established commercial production, studied for its electronic and magnetic properties that emerge from rare-earth-transition metal interactions. Potential applications focus on thermoelectric devices, magnetic refrigeration systems, and specialized semiconducting components where the unique phonon-electron coupling in rare-earth intermetallics could offer advantages in narrow temperature or field operating windows.

Quality & Standards

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.
