Graphite, 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 diamo… is a mineral of extremes. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity. In contrast, it is extremely resistant to heat and nearly inert in contact with almost any other material. These extreme properties give it a wide range of uses in metallurgy and manufacturing.Chemical Classification: Native elementColor: Steel gray to blackLuster: Metallic, sometimes submetallic or earthyStreak: What are the physical and chemical properties of graphite?Graphite, like diamond, is an allotrope of carbon. They are very similar to each other but the structure of the atom affects the chemical and physical properties. Graphite is made of layers of carbon atoms. These layers can slide over each other very easily. This means that it is very soft.See all results for this Is carbon and graphite the same thing?Carbon and graphite are both carbon forms where graphite is an allotrope of carbon and the most stable form of carbon. Carbon is a nonmetal that people knew since ancient times. Human beings used different forms of carbon, that we name as carbon allotropes, such as charcoal, graphite soot and diamond.See all results for this What is the different between graphite and coal?As nouns the difference between coal and graphite is that coal is (uncountable) a black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel while graphite is an allotrope of carbon consisting of planes of carbon atoms arranged in hexagonal arrays with the planes stacked loosely that is used as a dry lubricant and in "lead" pencils.See all results for this question

What Are the Properties of Graphite? (with pictures)

One of the more interesting properties of graphite is its conductivity. Graphite conducts electricity, which is unusual for a substance that is not a metal, especially since at least one other elemental carbon allotrope, diamond, is not conductive at all and is in fact a very good Graphite characteristicsHigh Degree Purity.
