Graphite, on the other hand, is a soft slippery solid that is a good conductor of both heat and electricity.Carbon as diamond is the most expensive and brilliant of all the natural gemstones and the hardest of the naturally occurring abrasives. In microcrystalline and nearly amorphous form, it is used as a black pigment, as an adsorbent, as a fuel, as a filler for rubber, and, mixed with clay, as the “lead” of pencils.

Isolated finds around the world in regions where no sources are indicated have not been uncommon.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 (C), nonmetallic chemical element in Group 14 (IVa) of the periodic table.
