· LuB2

Lutetium diboride (LuB₂) is a ceramic compound belonging to the hexaboride family of refractory materials, characterized by extremely high hardness and thermal stability. It is primarily investigated in research and aerospace contexts for extreme-environment applications where conventional ceramics fail, including high-temperature structural components, cutting tools, and thermal protection systems. LuB₂ offers advantages over more common borides through its combination of chemical inertness, resistance to oxidation at elevated temperatures, and mechanical robustness, though its rarity, cost, and processing complexity limit widespread commercial adoption compared to established alternatives like tungsten carbide or zirconia.

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.
