What is densified silica fume? – microsilica-fume.com
Densified silica fume is produced by treating undensified silica fume to increase the bulk density up to a maximum of about 400 to 720kg/m . This increase in bulk density is usually accomplished by tumbling the silica-fume particles in a silo, which causes surface charges to build up.
