· JVASP-99364· LaCo9Si4

LaCo9Si4 is a lanthanum-cobalt-silicon intermetallic compound belonging to the rare-earth transition metal family, primarily of research and development interest rather than mature commercial production. This material is investigated for potential applications in hydrogen storage, magnetic devices, and high-temperature structural applications due to the favorable properties imparted by lanthanum and cobalt combinations. Engineers would consider this material in emerging energy storage systems and specialty alloy development where rare-earth intermetallics offer advantages in hydrogen absorption capacity or magnetic performance over conventional alternatives.

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.
