· La3Ni

La₃Ni is an intermetallic compound in the lanthanum-nickel system, representing a rare-earth metallic phase with potential for hydrogen storage and electrochemical applications. This material is primarily of research interest rather than established commercial production, studied for its ability to absorb and release hydrogen reversibly, making it relevant to energy storage and battery technologies. Engineers consider La₃Ni-based compositions as alternatives to conventional nickel-metal hydride (NiMH) battery materials, valued for their enhanced hydrogen capacity and cycling stability in specialized 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.
