Aerolyst®

Product range


Aerolyst® is Evonik’s trademark for formed metal fumed oxides for use as catalyst supports or catalysts. The Aerolyst® 3000 series is based on Evonik’s AEROSIL®, a fumed silica with very high purity whereas the Aerolyst® 7700 series is based on AEROXIDE® TiO2 P 25 fumed titania. These products have advantages such as a narrow pore size distribution (no micro-pores!), a high pore volume, excellent strength and attrition properties.
