· Ti2 O4

Ti₂O₄ is a mixed-valence titanium oxide semiconductor belonging to the Magnéli phase family of reduced titanium oxides. This material exhibits interesting electronic and ionic transport properties due to its partially reduced structure, making it relevant for energy storage and electrochemical applications where titanium oxides are traditionally employed. While not yet widely commercialized, Ti₂O₄ and related Magnéli phases are actively researched for battery electrode materials, electrochemical capacitors, and gas-sensing devices due to their enhanced conductivity compared to stoichiometric TiO₂, and engineers evaluating advanced oxide semiconductors for high-temperature or high-energy-density applications should consider this material family.

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.
