carbon | Facts, Uses, & Properties | Britannica
Elemental carbon exists in several forms, each of which has its own physical characteristics. Two of its well-defined forms, diamond and graphite, are crystalline in structure, but they differ in physical properties because the arrangements of the atoms in their structures are dissimilar.A third form, called fullerene, consists of a variety of molecules composed entirely of carbon.

C is for Cast Iron – MetalsAndAlloysBlog
Graphite is the equilibrium high-carbon phase in cast irons and it can form from the melt either as a primary phase or as part of the iron + graphite eutectic. Under more rapid cooing, usually achieved industrially by having heat sinks, called chills, in a mould, graphite is supressed in favour of metastable cementite.

Exfoliation of Graphite. Shearing away sheets of graphene from bulk graphite is a process known as 'exfoliation', much like how we scrape dead skin off our bodies with scratchy rocks. In the graphene world, exfoliation first came to light when some adhesive tape was used to peel graphene layers away from some pencil smudges!

Graphite – Acervo Lima
Graphite (or, rarely, graphite) is a mineral, one of the allotropes of carbon.Unlike diamond, graphite is an electrical conductor.That is why it has applications in electronics, such as electrodes and batteries.Because of its high melting point, the material also has applications as refractories, such as crucibles for casting steel.Graphite can be dissolved in chlorosulfuric acid.

Preferably, graphite is arranged in layers, each of these layers is a separate supra-molecule called graphene (refer Figure 2). The ordering process is started by heat treatment up to 3000 °C in inert atmosphere. The original carbon material contains multiple small domains of graphene molecules known as basic structural units (BSU).
