· JVASP-142235· TbCo9Si2

TbCo9Si2 is a ternary intermetallic compound combining terbium, cobalt, and silicon, belonging to the rare-earth transition metal silicide family. This material is primarily of research interest for permanent magnet and magnetocaloric applications, where the rare-earth terbium provides strong magnetic moments and the cobalt-silicon framework offers structural stability. Engineers consider this composition for high-performance magnetic devices and potential cryogenic refrigeration systems where conventional cooling is impractical, though adoption remains limited to specialized applications due to cost and the availability of more established rare-earth alternatives.

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.
