Graphite - Wikipedia

Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.

SGS GRAPHITE CAPABILITIES

flake (>80 mesh) graphite grading better than 95% carbon is suitable for use in lithium batteries. Flotation is a common means of processing graphite but other approaches can be necessary, depending on the concentrate grade required. Further upgrading of the flotation concentrate to grades greater than 99.5% carbon is generally achieved through
