Making a liquid solid
Gelling is the process by which a liquid become viscous and eventually a solid. Colloidal silica particles form gels by linking together along siloxane bridges in branched chains, resulting in a contiguous gel network. The formed network prohibits liquid transport within the gel volume, but can still retain a liquid component through capillary action. In battery applications, sulfuric acid is retained in the gel; while in ground consolidation, it is water that is retained.
