What is Titanium Suboxide?
Ti4O7 Titanium Suboxide — Magnéli-Phase Conductive Ceramic Powder
Titanium Suboxide is an Aurexene Ti4O7 Magnéli-phase conductive ceramic powder. It is a material input for formulation, electrode, and black-pigment qualification; final-system performance requires matched testing.

Quick Answer
Aurexene Titanium Suboxide is a Ti4O7 Magnéli-phase conductive ceramic powder. Supplier-listed material values inform screening; phase, powder, electrode, and finished-system qualification remain separate evidence layers.
What It Is Not
- Titanium Suboxide is an oxygen-deficient titanium-oxide family, not TiO2 titanium dioxide or TiN titanium nitride.
When Not to Use It
- Do not use Titanium Suboxide when stoichiometric TiO2 behavior, electrical insulation, or a light-colored oxide is required.
Intrinsic Screening Summary
- Identity screen
- Tetratitanium heptoxide (Ti4O7), Magneli-phase titanium suboxide; Rutile-related crystal structure with crystallographic shear planes; blue-black fine powder
- Intrinsic feature
- Ordered oxygen vacancies and mixed Ti3+/Ti4+ valence states create a partially filled d-band that supports metallic-like conductivity; confirm performance in the final system.
- Material-level integration
- Disperse in water or organic media with appropriate dispersants and surfactants. Maintain an inert or vacuum atmosphere above 600 C to limit re-oxidation to TiO2. Use when evaluating Conductive Materials / Optical Black Coatings / Energy Storage formulations or systems.
