The AEROSIL®- manufacturing process can also be applied to produce fumed aluminum and titanium oxides. The treatment processes mentioned previously are also applicable here and result in a wide range of fine particle products with extraordinary properties.



AEROXIDE® Alu C is a pure aluminum oxide with a hydrophilic character. In water it displays a positive zeta potential. Its primary use is as a free-flow agent and it regulates triboelectric effects.




AEROXIDE® TiO2 P 25 is a titanium dioxide without pigment properties. Thanks to its purity and fine particle size, it may be used as a catalyst support or as a heat stabilizer for silicone rubber.

Positive effects:

  • Free-flow in powder coatings

  • Heat stabilization of silicone elastomers

  • Optimization of adsorption properties, e.g. inkjet applications
