· JVASP-133908· Ba2HfO3

Ba₂HfO₃ is a complex oxide ceramic composed of barium, hafnium, and oxygen, belonging to the family of perovskite-related compounds. This material is primarily investigated in research and development contexts for applications requiring high-temperature stability and chemical inertness, particularly in thermal barrier coatings, refractory systems, and advanced nuclear or aerospace environments where superior thermal and chemical resistance are essential. Its hafnium-based composition makes it notable for applications demanding resistance to extreme conditions, as hafnium oxides are among the most refractory ceramic materials known.

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.
