The characteristic properties of graphite and diamond might lead you to expect that diamond would be more stable than graphite. This is not what is observed experimentally. The standard enthalpy of formation of diamond ( H o f = 2.425 kJ/mol) is slightly larger than the enthalpy of formation of graphite, which is the most stable form of carbon at 25 o C and 1 atm pressure.
7/9/1990· The graphite is present in flake form and as such greatly reduces the tensile strength of the matrix. It is possible to produce all grades of iron of ASTM Specifiion for Gray Iron Castings (A 48-64) by merely adjusting the carbon and silicon content of the iron.

Graphene (/ ˈ ɡ r æ f iː n / [1]) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeyco lattice. [2] [3] The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.

Graphite 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.
