· JVASP-148895· LuB2Ir3

LuB2Ir3 is an intermetallic ceramic compound combining lutetium, boron, and iridium—a rare-earth metal boride with iridium. This is primarily a research material rather than an established commercial ceramic, investigated for ultra-high-temperature and extreme-environment applications where conventional refractories reach their limits. The material's appeal lies in its potential for aerospace propulsion systems, nuclear thermal protection, and high-temperature structural applications where density, stiffness, and oxidation resistance are critical; however, manufacturing cost, brittleness, and limited industrial track record make it a specialized choice for cutting-edge engineering rather than mainstream 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.
