· Ti4O5

Ti₄O₅ is a mixed-valence titanium oxide ceramic, a Magnéli-phase compound that sits between the extremes of titanium dioxide (TiO₂) and titanium monoxide (TiO). This material is primarily of research and development interest rather than widely commercialized, investigated for its potential in electrochemistry, photocatalysis, and energy storage applications where its defect structure and electronic properties offer advantages over conventional titania. Ti₄O₅ and related Magnéli phases are studied as candidates for improved performance in photocatalytic water treatment, electrochemical supercapacitors, and lithium-ion battery materials, where the material's reduced bandgap and enhanced conductivity compared to stoichiometric TiO₂ make it technically attractive.

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.
