· Tb4 Co4 Si4

Tb₄Co₄Si₄ is an intermetallic compound combining terbium (a rare-earth element), cobalt, and silicon in a stoichiometric ratio. This is a research-phase material studied primarily for its electronic and magnetic properties rather than structural applications; it falls within the family of rare-earth transition-metal silicides being explored for specialized functional device applications. The compound's notable stiffness and hardness characteristics, combined with its semiconducting behavior, position it as a candidate material for high-temperature electronics, magneto-responsive devices, or advanced sensor systems where rare-earth intermetallics offer performance advantages over conventional semiconductors.

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.
