· JVASP-106068· HfTaB2

HfTaB2 is a hafnium-tantalum boride ceramic compound that belongs to the ultra-high-temperature ceramic (UHTC) family. This material combines the refractory properties of hafnium and tantalum with boride ceramic strength, making it a candidate for extreme thermal environments where conventional ceramics fail. While primarily in the research and development phase, HfTaB2 is being investigated for hypersonic vehicle protection, rocket nozzles, and thermal barrier applications where materials must withstand sustained temperatures well beyond 2000°C while maintaining structural integrity.

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.
