These small diamonds are made by squeezing graphite under high temperatures and pressures for several days or weeks and are primarily used to make things like diamond tipped saw blades.Although they posses very different physical properties, graphite and diamond differ only in their crystal structure.This black soot, also known as lampblack, gas black, channel black or carbon black, is used to make inks, paints and rubber products.It can also be pressed into shapes and is used to form the cores of most dry cell batteries, among other things.Carbon-14, a radioactive isotope of carbon with a half-life of 5,730 years, is used to find the age of formerly living things through a process known as radiocarbon dating. Scientists know that a small amount of naturally occurring carbon is carbon-14.Although carbon-14 decays into nitrogen-14 through beta decay, the amount of carbon-14 in the environment remains constant because new carbon-14 is always being created in the upper atmosphere by cosmic rays.Living things tend to ingest materials that contain carbon, so the percentage of carbon-14 within living things is the same as the percentage of carbon-14 in the environment.

These two forms have identical physical properties but different crystal structures.

Diamond, the third naturally occurring form of carbon, is one of the hardest substances known.

Although naturally occurring diamond is typically used for jewelry, most commercial quality diamonds are artificially produced.

Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.

Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.
