· JVASP-39635· ZrH3

ZrH₃ is a zirconium hydride intermetallic compound belonging to the metal hydride family, formed by hydrogen absorption into zirconium. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, valued for its unique combination of low density and metallic properties that make it useful in applications where hydrogen storage, neutron moderation, or lightweight structural behavior is critical.

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.
