Cr1 O2
semiconductor· Cr1 O2
Cr₁O₂ (chromium dioxide) is a ferrimagnetic ceramic oxide semiconductor with a tetragonal crystal structure, notable for its unusual magnetic properties among oxide materials. Historically important as the magnetic layer in cassette tapes and magnetic recording media, it has been studied for potential applications in spintronics, magnetic sensors, and catalysis due to its half-metallic character and tunable electronic properties. Engineers consider this material primarily for niche applications requiring magnetic oxides with specific conductivity characteristics, though it has been largely superseded by modern alternatives in consumer electronics.

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.
