· JVASP-133909· BaHfO2

Barium hafnate (BaHfO2) is a dense ceramic compound combining barium oxide with hafnium oxide, belonging to the perovskite family of materials. While primarily investigated in research contexts, BaHfO2 is explored for high-temperature structural applications and as a potential thermal barrier or environmental barrier coating material, particularly in aerospace systems where hafnium-based ceramics offer superior oxidation and corrosion resistance compared to conventional oxides. Its notable appeal lies in the combination of hafnium's refractory properties and chemical stability, making it a candidate for extreme-environment 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.
