· JVASP-39372· Ni3H

Ni₃H is a nickel-hydrogen interstitial compound formed when hydrogen dissolves into or reacts with nickel metal, creating a hydride phase. This material is primarily of research and specialized industrial interest rather than a widespread engineering commodity. It appears in hydrogen storage systems, catalytic applications, and materials science studies exploring metal-hydrogen interactions, where its formation and decomposition kinetics are relevant to understanding hydrogen embrittlement, fuel cell technologies, and advanced energy storage systems.

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.
