ceramic

· Dy4 Al4 O12

Dy4Al4O12 is a rare-earth aluminate ceramic compound combining dysprosium oxide with aluminum oxide in a stoichiometric ratio. This material belongs to the family of rare-earth aluminates, which are primarily investigated for high-temperature structural and functional applications where conventional ceramics reach their thermal limits. The dysprosium addition imparts enhanced thermal stability and potential luminescent or magnetic properties, making it of interest in advanced aerospace, thermal barrier coating, and solid-state lighting research contexts.

Regulatory Screening

Environmental

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.
