Anomalously stable dispersions of graphite in …

We show that graphite particles are dispersed stably in water/acetone mixtures. Acetone facilitates disintegration of the graphite particles and their aggregates during sonication. Fine graphite particles are stabilized by the electrostatic repulsion due to negative charges on the graphite particle surfaces.

Water-Based Dispersion - gk-graphite.com

To produce graphite dispersions, very finely ground graphite particles are dispersed in a liquid. This liquid is often water. Dispersions with fine-grained graphite improve forging operations and are used in the warm and hot forging process, while coarser-grained graphite dispersions withstand the high temperatures created by the lubrication of mandrel bars and rollers.
