· JVASP-42468· SmFe2O4

SmFe2O4 is a samarium iron oxide ceramic belonging to the spinel ferrite family, composed of samarium and iron oxide in a cubic crystalline structure. This material is primarily of research interest for magnetic and electromagnetic applications, particularly in high-temperature environments where ferrites offer superior stability compared to metallic magnets. Its potential applications span microwave devices, magnetic recording media, and specialized electromagnetic components in aerospace and defense sectors, though it remains less commercially prevalent than standard ferrites like nickel-zinc or manganese-zinc varieties.

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.
