Highest melting point of all metals. Made into filaments for vacuum tubes and electric lights. Also as contact points in cars. Combined with calcium or magnesium it makes phosphors. Tungsten carbide is extremely hard and is used for making cutting tools and abrasives. Occurs in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4]. _PccntqMOoI Tungsten

Carbon was discovered in prehistory and was known in the forms of soot and charcoal to the earliest human civilizations.

In 1772, Antoine Lavoisier showed that diamonds are a form of carbon; when he burned samples of charcoal and diamond and found that neither produced any water.

In 1779, Carl Wilhelm Scheele showed that graphite burned to form carbon dioxide and so must be another form of carbon. From the Latin word carbo, charcoal 74 1783 Fausto and Juan Jose de Elhuyar Spain From the Swedish words "tung sten" meaning "heavy stone" (the origin of the symbol W is "wolfram ", named after the tungsten mineral wolframite)

Pure carbon has extremely low toxicity to humans and can be handled safely in the form of graphite or charcoal

About 20% of the weight of living organisms is carbon

The major use of carbon other than food and wood is in the form of hydrocarbons, most notably the fossil fuel methane gas and crude oil.

Graphite is used for pencil tips, high temperature crucibles, dry cells, electrodes and as a lubricant.

Diamonds are used in jewelry and in industry for cutting, drilling, grinding, and polishing.

Carbon black is used as the black pigment in printing ink.
