· JVASP-103412· Ti4O3

Ti₄O₃ is a reduced titanium oxide ceramic compound that belongs to the Magnéli phase family of substoichiometric titanium oxides. This material exhibits metallic conductivity despite its ceramic nature, making it distinct from conventional insulting oxides like TiO₂. While primarily of research interest rather than a widespread industrial commodity, Ti₄O₃ and related Magnéli phases show promise in electrochemical applications, thermal management, and specialized electronic devices where the combination of ceramic durability with electrical conductivity is advantageous.

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.
