All artificially produced graphite is of the alpha type.In addition to its use as a lubricant, graphite, in a form known as coke, is used in large amounts in the production of steel.Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. 1979, 1986 © Harper Collins Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012 Cite This Source (rā'dē-ō-mět'rĭk) A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).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.Once an organism dies, it no longer ingests much of anything.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.
It can also be pressed into shapes and is used to form the cores of most dry cell batteries, among other things.
A single buckyball consists of 60 or 70 carbon atoms (C) linked together in a structure that looks like a soccer ball.
They can trap other atoms within their framework, appear to be capable of withstanding great pressures and have magnetic and superconductive properties.
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.
