Beschreibung
Zusammenfassung:	The present invention concerns a method for making a silicon dioxide suspension comprising the process steps: providing a silicon dioxide powder and a liquid; mixing the silicon dioxide powder with the liquid to obtain a slurry; treating the slurry with ultrasound to obtain a precursor suspension; passing at least a part of the precursor suspension through a first multi-step filter device, wherein the first multi-step filter device has specific filter steps as disclosed herein. The invention also concerns a silicon dioxide suspension thus obtainable, granulates and consequential products obtainable therefrom.
