· Tb1 Co3 B2

Tb₁Co₃B₂ is an intermetallic compound combining terbium (a rare-earth element), cobalt, and boron, classified as a semiconductor material. This is a research-phase compound studied primarily for its magnetic and electronic properties rather than as an established commercial material. The rare-earth–transition-metal boride family shows promise in high-performance magnetic devices and advanced electronics applications where precise control of electronic band structure and magnetic behavior is needed.

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.
