· JVASP-14727· ZrB

ZrB is a refractory ceramic compound combining zirconium and boron, belonging to the family of ultra-high-temperature ceramics (UHTCs). This material is engineered for extreme thermal and oxidation resistance, making it a candidate for aerospace propulsion systems, hypersonic vehicle structures, and high-temperature structural applications where conventional metals and ceramics fail.

Export Control

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.
