· HfErO3

HfErO3 is a mixed rare-earth oxide ceramic compound combining hafnium and erbium oxides, belonging to the family of high-entropy or complex perovskite-like ceramics. This is primarily a research material under investigation for advanced high-temperature applications, where its thermal stability and potential dielectric properties may offer advantages in extreme environments. Interest in this composition centers on thermal barrier coatings, refractory applications, and solid-state energy conversion systems where conventional oxides face limitations.

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.
