· JVASP-123738· HfH

Hafnium hydride (HfH) is a ceramic compound formed by the hydridation of hafnium metal, belonging to the transition metal hydride family. It is primarily investigated in nuclear and aerospace research contexts for applications requiring high-temperature stability, neutron absorption control, and chemical inertness. HfH is notable for its potential use in nuclear reactor control systems and as a material for studying metal-hydrogen interactions, though it remains largely confined to research and specialized defense applications rather than mainstream industrial use.

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.
