· JVASP-9728· DyAsO4

Dysprosium arsenate (DyAsO4) is a rare-earth ceramic compound belonging to the zircon-family phosphate/arsenate mineral class, characterized by a tetragonal crystal structure and high density. While primarily a research and development material rather than a widely commercialized product, DyAsO4 is investigated for high-temperature applications and specialized optical/photonic systems where rare-earth dopants are leveraged for luminescence and thermal stability. Engineers consider rare-earth arsenates in niche applications requiring chemical inertness at elevated temperatures, though practical adoption remains limited compared to established alternatives like rare-earth phosphates or oxides.

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.
