FUMED SILANIZED AND GROUND SILICA – EVONIK DEGUSSA GmbH
It is known that a high-dispersity silica with a surface area of approx. 300 m 2 /g can be ground in a pin mill. The grindometer value achieved is initially 25 μm for the uncompacted silica. If this silica is compacted to 50 g/l, the grindometer value rises to 30 μm, and, in the event of further compaction to 75 g/l, even to about 40 μm.
