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.
