· JVASP-15223· Dy2Al3Si2

Dy2Al3Si2 is an intermetallic compound combining dysprosium (a rare earth element) with aluminum and silicon, forming a ternary metallic phase that belongs to the family of rare-earth aluminum silicides. This material is primarily of research and development interest rather than established commercial production, studied for potential applications where rare-earth strengthening and thermal stability are valuable. Engineers would consider this compound family for advanced high-temperature structural applications or functional materials where the unique combination of rare-earth and light-metal constituents offers advantages over conventional alloys, though practical engineering adoption remains limited pending further development and cost optimization.

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.
