Carbon dating process

Yet another form, called amorphous carbon, has no crystalline structure.

Other forms—such as coke—are sometimes called amorphous, but X-ray examination has revealed that these substances do possess a low degree of crystallinity.

Coral and the shells of oysters and clams are primarily calcium carbonate.Q-carbon, which is created by rapidly cooling a sample of elemental carbon whose temperature has been raised to 4,000 K (3,727 °C [6,740 °F]), is harder than diamond, and it can be used to manufacture diamond structures (such as diamond films and microneedles) within its matrix. Each of the “amorphous” forms of carbon has its own specific character, and, hence, each has its own particular applications.All are products of oxidation and other forms of decomposition of organic compounds.Carbon is the cosmic product of the “burning” of helium, in which three helium nuclei, atomic number 4, fuse to produce a carbon nucleus, atomic number 12.In the crust of Earth, elemental carbon is a minor component.

Because it conducts electricity but does not melt, graphite is also used for electrodes in electric furnaces and dry cells as well as for making crucibles in which metals are melted.
