· JVASP-48155· MgFe2O4

MgFe2O4 is a magnesium iron oxide ceramic belonging to the spinel family of materials, characterized by its mixed-valence iron oxide structure. It is primarily employed in magnetic and electromagnetic applications, including magnetic cores for inductors, transformers, and microwave devices, where its ferrimagnetic properties enable efficient energy conversion. The material is notable for its thermal stability and chemical inertness, making it suitable for high-frequency electronics and environments where conventional ferrites may degrade; it also finds use in catalytic applications and as a component in advanced ceramic composites.

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.
