· JVASP-106681· ZrNbB4

ZrNbB4 is an experimental refractory metal boride compound combining zirconium, niobium, and boron—materials known for exceptional hardness and thermal stability. This is a research-phase material primarily investigated for ultra-high-temperature structural applications where conventional superalloys reach their limits, particularly in aerospace and materials science laboratories studying next-generation thermal protection systems and wear-resistant coatings.

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.
