· JVASP-131735· Dy8H

Dy8H is a dysprosium hydride ceramic compound, part of the rare-earth hydride family used primarily in specialized high-temperature and nuclear applications. This material is valued in aerospace and nuclear engineering contexts where its thermal stability, neutron absorption characteristics, and high density make it suitable for shielding, moderator, or structural roles in extreme environments. Dysprosium hydrides are less common than other rare-earth ceramics but offer distinct advantages in applications requiring both thermal performance and nuclear properties.

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.
