Graphite charge
WebFeb 1, 2024 · Graphite is a soft, slippery feel, and is used in pencils and as a dry lubricant for things like locks. It has a lower density than diamond. It is insoluble in water and organic solvents – for the same reason that diamond is insoluble. Graphite has a high melting point, similar to that of a diamond. http://large.stanford.edu/courses/2024/ph240/friedman2/
