Graphite is the only non-metal element that is a good conductor of electricity and heat. Its softness and streak make graphite useful in making lead for pencils. Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flakes. It breaks into minute, flexible flakes that easily slide over one another.
For example, the graphite-oil agglomerates can be separated from the water and graphite grinding aid by filtering with bar sieves or screens which predominately retain the graphite-oil agglomerates, but pass water and unagglomerated graphite grinding aid. The result is a physical separation of the graphite grinding aid from graphite.
