Some additional information about graphite.
According to the USGS, U.S. consumption of natural graphite in 2004-05 averaged 43,800 tonnes in end uses such as refractories, steelmaking, expanded graphite, brake linings, and foundry facings-lubricants. GAN (Graphite Advocate News) import-export statistics for 2006 and 2007 indicate the consumption will continue at that level unless steelmaking carbon raiser takes a drastic drop.
Steelmaking: Natural graphite in this end use mostly goes into carbon raising in molten steel, although it can be used to lubricate the dies used to extrude hot steel. Supplying carbon raiser is very competitive, therefore subject to cut-throat pricing from alternatives such as synthetic graphite powder, petroleum coke, and other forms of carbon. A carbon raiser is added to increase the carbon content of the steel to the specified level. A GAN consumption estimate based on USGS U.S. graphite consumption statistics indicates that 10,500 tonnes was used in this end-use in 2005.
Expanded Graphite (including foil and packings): Expanded graphite is made by immersing natural flake graphite in a bath of chromic acid, then concentrated sulfuric acid, which forces the crystal lattice planes apart, thus expanding the graphite. The expanded graphite can be used to make graphite foil or used directly as "hot top" compound to insulate molten metal in a ladle or red-hot steel ingots and decrease heat loss, or as firestops fitted around a firedoor (During a fire, the graphite expands and chars to resist fire penetration and spread.), or to make high-performance gasket material for high-temperature use. After being made into graphite foil, the foil is machined and assembled into the bipolar plates in fuel cells. The foil is made into heat sinks for laptop computers which keeps them cool while saving weight, and is made into a foil laminate that can be used in valve packings or made into gaskets. Old-style packings are now a minor member of this grouping: fine flake graphite in oils or greases for uses requiring heat resistance. A GAN estimate of current U.S. natural graphite consumption in this end use is 8,000 tonnes.
Brake Linings: Natural amorphous and fine flake graphite are used in brake linings or brake shoes for heavier (nonautomotive) vehicles, and became important with the need to substitute for asbestos. This use has been important for quite some time, but nonasbestos organic (NAO) compositions are beginning to cost graphite market share. A brake-lining industry shake-out with some plant closings has not helped either, nor has an indifferent automotive market. According to the USGS, U.S. natural graphite consumption in brake linings was 6,510 tonnes in 2005.
Foundry facings and lubricants: A foundry facing or mold wash is a water-based paint of amorphous or fine flake graphite. Painting the inside of a mold with it and letting it dry leaves a fine graphite coat that will ease separation of the object cast after the hot metal has cooled. Graphite lubricants are specialty items for use at very high or very low temperatures, as a wire die extrusion lubricant, an antiseize agent, a gear lubricant for mining machinery, and to lubricate locks. Having low-grit graphite, or even better no-grit graphite (ultra high purity), is highly desirable. It can be used as a dry powder, in water or oil, or as colloidal graphite (a permanent suspension in a liquid). An estimate based on USGS graphite consumption statistics indicates that 2,200 tonnes was used in this end-use in 2005.
Natural graphite is the substance used as the marking material ("lead") in common pencils, in zinc-carbon batteries, in electric motor brushes, and in some other minor uses.
CONDITIONS AND NOS: Sometimes NOS (NEW OLD STOCK) items can be very old and although they are new can have slight imperfections in them. This may because of the way they were made years ago or may have slight imperfections, bruises, scuffs or minor dings from being moved around the shelving over the years with other items bumping into them. We do our best to describe these imperfections (if any) in our listings when ever possible worth noting.
