Ba3Hf2O7
ceramic· JVASP-50923· Ba3Hf2O7
Ba3Hf2O7 is a barium hafnium oxide ceramic compound belonging to the pyrochlore family of materials, characterized by a complex crystal structure suitable for high-temperature applications. This material is primarily investigated in research contexts for thermal barrier coatings and solid oxide fuel cell (SOFC) electrolytes, where its thermal stability and ionic conductivity properties are leveraged; it offers potential advantages over conventional zirconia-based systems in extreme temperature environments, though industrial adoption remains limited compared to established 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.
