· JVASP-138447· Ca2HfO3

Calcium hafnium oxide (Ca₂HfO₃) is a complex ceramic compound combining alkaline earth and refractory metal oxide chemistries, belonging to the family of perovskite-related oxides. This material is primarily of research and developmental interest for high-temperature applications, thermal barrier systems, and advanced ceramic coatings where exceptional thermal stability and chemical inertness are required. Its hafnium content provides superior high-temperature performance compared to simpler oxides, making it relevant for aerospace and industrial environments where conventional ceramics degrade, though it remains less established in production than yttria-stabilized zirconia or other mature thermal barrier materials.

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.
