· Lu5Si3B

Lu5Si3B is a rare-earth silicide boride ceramic compound combining lutetium, silicon, and boron—a research-phase material being investigated for ultra-high-temperature structural applications. This material family is of particular interest for aerospace and thermal management systems where exceptional oxidation resistance and high-temperature strength are required, though it remains largely experimental and not yet widely commercialized compared to established ceramics like silicon carbide or alumina.

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.
