· Dy4 Co4 Si4

Dy₄Co₄Si₄ is an intermetallic compound combining dysprosium (a rare-earth element), cobalt, and silicon in a 1:1:1 stoichiometric ratio. This material belongs to the rare-earth transition metal silicide family and is primarily of research interest rather than established in widespread industrial production. The compound is investigated for potential applications in magnetic materials, high-temperature structural applications, and advanced semiconducting devices, leveraging the magnetic properties of dysprosium and the structural stability imparted by the intermetallic framework.

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.
