· JVASP-138449· CaHfO2

Calcium hafnate (CaHfO₂) is a ceramic compound combining calcium oxide with hafnium oxide, belonging to the family of refractory perovskite-related oxides. It is primarily investigated for high-temperature structural and thermal applications where exceptional thermal stability and chemical inertness are required. This material is particularly notable in aerospace and nuclear contexts where hafnium-containing ceramics offer superior resistance to oxidation and thermal cycling compared to conventional refractory alternatives.

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.
