Fumed Metal Oxides

Evonik’s™ AEROXIDE® range is comprised of fumed titanium dioxide and fumed aluminium oxide, produced in a manufacturing process analogous to that used to make AEROSIL® fumed silica.

Two of the most popular grades are AEROXIDE® Alu C and AEROXIDE® TiO2 P 25. AEROXIDE® Alu C is a pure aluminium oxide grade which is primarily used as a free flow agent and to regulate triboelectric effects. AEROXIDE® TiO2 P 25 is a pure titanium dioxide grade and is commonly used as a heat stabiliser in silicone rubber, photocatalytic air purifier or in the creation of self-cleaning surfaces.


    • Fumed titanium dioxide and aluminium oxide.
    • Hydrophilic and hydrophobic grades available.

    • High specific surface areas.

    • High purity.


    • Highly efficient free flow additive (Alu grades).

    • Anti-blocking agent in PET films (Alu C).

    • Cationic charge helps to immobilize inks and pigments in high quality paper coatings (Alu grades)

    • Photocatalytic effect: sterilisation, air purification, self-cleaning (P 25/PF 2).

    • Heat stabilizer in silicone rubber (P 25).

    • High level of UV absorption (T 805).

Typical Applications

    • Improving the thermal stability of silicone rubber.

    • Free-flow agent for powder coatings.

    • Anti-blocking agent in PET films.

    • Photocatalytic applications e.g. wastewater treatment and reduction of NOx gases.

AEROXIDE®, AERODISP® and AEROPERL® - Titanium Dioxide as a Photocatalyst

This brochure looks at the use of fumed titanium dioxide as a means of photocatalytically breaking down microbes and air pollutants. Another phenomena observed is the generation of a superhydrophilic surface; employed in self-cleaning surfaces.
