Porous, carbon containing material from spherical particles useful e.g. as an optical or infrared opacifiers, adsorbents, catalyst supports, and functional filler in composites or polymers, or as electro-chemical storage

摘要

Porous, carbon containing material from spherical particles, where the average particle size of the material is less than 20 microns, is claimed. An independent claim is included for preparing the material comprising producing the particles from a sol-gel process by sedimentation in a solution.
