· 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.
