· NbHfON2

NbHfON2 is a refractory ceramic compound combining niobium, hafnium, oxygen, and nitrogen—part of the high-entropy or complex metal oxynitride family designed for extreme-temperature applications. This material is primarily investigated in research and development contexts for its potential to maintain mechanical integrity and oxidation resistance at temperatures where conventional ceramics degrade, making it of interest for next-generation aerospace and energy systems. The addition of nitrogen to the hafnium–niobium oxide matrix is engineered to improve fracture toughness and thermal shock resistance compared to single-phase oxides, positioning it as a candidate for thermal protection systems and ultra-high-temperature structural components.

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.
