Graphite Chemical Properties,Usage,Production
Chemical Properties
soft dark grey solid
Chemical Properties
Graphite is crystallized carbon and usually appears as soft, black scales. There are two types of graph ite, natural and artificial (activated). Natural and synthetic graphite may be mixed with each other or contain other additives.
Uses
For "lead" pencils, refractory crucibles, stove polish; as pigment, lubricant, graphite cement; for matches and explosives, commutator brushes, anodes, arc-lamp carbons, electroplating; polishing Compounds, rust and needle-paper; coating for cathode ray tubes; moderator in nuclear piles.
Uses
Graphite has been used alone to make refractory products for the lower blast furnace linings, and electrodes for steel and aluminum production. They are also commonly used in conjunction with other refractory raw materials. These materials are highly refractory nonwettable materials and are useful refractories in nonoxidizing environments. Carbon blacks are co
Uses
Similar to those of natural graphite in refractories and electrical products
Definition
An allotrope of CARBON. Graphite is a good conductor of heat and electricity. The atoms are arranged in layers which cleave easily and graphite is used as a solid lubricant.
General Description
A mineral form of the element carbon. Hexagonal crystals or thin leaf-like layers. Steel-gray to black with a metallic luster and a greasy feel. An electrical conductor. Used for high-temperature crucibles, as a lubricant and in "lead" pencils.
Reactivity Profile
GRAPHITE is non-flammable in bulk form, but combustible. A reducing agent. Mixtures of graphite dust and air are explosive when ignited.Reacts violently with very strong oxidizing agents such as fluorine, chlorine dioxide, and potassium peroxide. Almost inert chemically when in bulk form. Keep away from ignition sources and oxidizing agents.
Health Hazard
Pure synthetic graphite acts as an inert or nuisance dust.
Industrial uses
Graphite is a form of carbon. It was formerlyknown as black lead, and when first used forpencils was called Flanders’ stone. It is a naturalvariety of elemental carbon with a grayishblackcolor and a metallic tinge.
Carbon and graphite have been used inindustry for many years, primarily as electrodes,arc carbons, brush carbons, and bearings.In the last decade or so, development ofnew types and emergence of graphite fibers asa promising reinforcement for high-performancecomposites have significantly increasedthe versatility of this family of materials.
Potential Exposure
Natural graphite is used in foundry facings, steel making lubricants, refractories, crucibles, pencil “lead,” paints, pigments, and stove polish. Artificial graphite may be substituted for these uses with the excep tion of clay crucibles; other types of crucibles may be pro duced from artificial graphite. Additionally, it may be used as a high temperature lubricant or for electrodes. It is uti lized in the electrical industry in electrodes, brushes, con tacts, and electronic tube rectifier elements; as a constituent in lubricating oils and greases; to treat friction elements, such as brake linings; to prevent molds from sticking together; and in moderators in nuclear reactors. In addition, concerns have been expressed about synthetic graphite in fibrous form. Those exposed are involved in production of graphite fibers from pitch or acrylonitrile fibers and the manufacture and use of composites of plastics, metals, or ceramics reinforced with graphite fibers.
Shipping
UN1362 Carbon, activated, Hazard Class: 4.2; Labels: 4.2-Spontaneously combustible material, International.
Purification Methods
Treat graphite with hot 1:1 HCl. Then filter, wash and the dried powdered is heated in an evacuated quartz tube at 1000o until a high vacuum is obtained. Cool this and store it in an atmosphere of helium [Craig et al. J Phys Chem 60 1225 1956].
Incompatibilities
Graphite is a strong reducing agent and reacts violently with oxidizers, such as fluorine, chlorine trifluoride, and potassium peroxide. Forms an explosive mixture with air. May be spontaneously combustible in air.
Waste Disposal
Do not incinerate. Carbon (graphite) fibers are difficult to dispose of by incineration. Waste fibers should be packaged and disposed of in a land fill authorized for the disposal of special wastes of this nature, or as otherwise may be required by law.
