Graphite is an allotrope of elemental carbon, carbon atoms surrounding each link with the other three carbon atoms (the arrangement was more of a hexagonal honeycomb-like) covalently bonded to form a covalent molecule. Since each carbon atom will emit an electron graphite, that electrons can move freely, and therefore belong to the graphite conductor. Graphite is one of the softest mineral, its uses include the manufacture of pencil lead, and a lubricant. Carbon is a nonmetallic element, located at the second cycle Group IVA of the periodic table. Latin for Carbonium, meaning "coal, charcoal," character "C" word by word plus stone charcoal "charcoal" word next to constitute, from the "charcoal" pronunciation. Crucible and related products made of graphite forming and refractory crucible and its related products, such as crucibles, retorts, plugs and nozzles, etc., with a high fire resistance, low thermal expansion, melting metal process by metal infiltration and When erosion is also stable, good thermal shock resistance at high temperatures and excellent conductivity, high purity graphite, graphite crucible so its related products are widely used in the process of direct molten metal. Traditional graphite clay crucible with flake graphite producing carbon content greater than normally graphite flake should be greater than mesh (- sieve), and the current key improvements abroad crucible production technology is the graphite type is used, with the flake size and quality greater flexibility followed by silicon carbide graphite crucible to replace the traditional clay graphite crucible graphite products, which is the steel industry with the introduction of technologies generated constant. Constant voltage technology can also be applied to make a small flake graphite, clay graphite crucible graphite packing, graphite and silicon carbide crucible, large flake ingredients only content, carbon content is reduced to graphite. Carbon is a very common element, which is widespread in many forms in the atmosphere and the earth's crust being. Elemental carbon has long been recognized and utilized a series of carbon compounds - organic matter is essential for life. Carbon is one of the components of cast iron, wrought iron and steel. Carbon bonded to form a large number of self compound chemically, in biologically and commercially important molecules. Most in vivo biological molecules contain carbon.
