· JVASP-37346· Ti3O2

Ti3O2 is a reduced titanium oxide ceramic compound that exists at the lower end of the titanium–oxygen phase diagram, sitting between metallic titanium and fully oxidized TiO2. This material represents a research-phase composition not commonly encountered in mainstream industrial production; it belongs to the family of substoichiometric titanium oxides that are primarily of scientific interest for understanding phase relationships and potential functional properties in the Ti-O system. Ti3O2 and related reduced oxides are investigated for niche applications requiring specific electronic or catalytic behavior, though conventional titanium grades and stoichiometric oxides (TiO2, Ti2O3) remain the industrial standards for most engineering roles.

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.
