HfTa
ceramic· JVASP-111050· HfTa
HfTa is a refractory ceramic compound combining hafnium and tantalum, two of the highest-melting-point elements in the periodic table. This material is primarily explored in extreme-temperature applications where conventional ceramics and metals fail, particularly in aerospace and materials research settings. Its appeal lies in exceptional thermal stability and potential for ultra-high-temperature structural applications, though it remains largely in the research and development phase rather than widespread industrial production.

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.
