Anyone has experience in how to make porous large size silica from fine
silica powders? Simple press method does not work for me since the tap
density of formed large size silica is way too high compared with fine
powders. The target is to have marcropores formation in formed large size
silica. I am thinking to add something together with fine powders while
press; then extract (remove) the "something" out but I have very hard time
to find that "something".
Any suggestions will be appreciated!
