· JVASP-56634· BaYFe4O7

BaYFe4O7 is a barium yttrium iron oxide ceramic belonging to the garnet or magnetoplumbite family of mixed-metal oxides. This compound is primarily studied in research contexts for its magnetic and dielectric properties, making it of interest in microwave devices, magnetic recording media, and ferrimagnetic applications where high-density iron oxide ceramics are needed. Its notable feature is the combination of barium and yttrium cations with iron oxide, which can yield useful ferrimagnetic behavior and thermal stability compared to simpler iron oxide ceramics.

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.
