Usage

Description

Glassy Carbon is a form of carbon material characterized by its amorphous structure, high purity, and unique properties such as high thermal and electrical conductivity, chemical inertness, and excellent mechanical strength. It is a non-graphitizable carbon material derived from the pyrolysis of organic precursors at high temperatures.

Uses

Used in Medical Applications:
Glassy Carbon is used as an implant material for its biocompatibility, corrosion resistance, and mechanical strength, making it suitable for orthopedic and dental implants.
Used in Analytical Chemistry:
Glassy Carbon is used as an electrode material in various electrochemical applications due to its chemical inertness, low background current, and wide potential window.
Used in Aerospace Industry:
Glassy Carbon is used as a component in heat shields and thermal protection systems for its high-temperature stability and thermal shock resistance.
Used in Electronics:
Glassy Carbon is used as a substrate or encapsulant for electronic devices due to its excellent thermal and electrical properties, as well as its dimensional stability.
Used in Energy Storage:
Glassy Carbon is used in the development of supercapacitors and batteries as an electrode material, taking advantage of its high surface area and electrical conductivity.
Used in Environmental Applications:
Glassy Carbon is used as a catalyst support or adsorbent in air and water purification processes due to its high surface area and chemical inertness.
Used in Metallurgical Applications:
Glassy Carbon is used as a crucible material for melting and holding high-purity metals, as it can withstand high temperatures and is resistant to chemical attack.
Used in Art and Archaeology:
Glassy Carbon is used in the conservation and restoration of artifacts, as well as in the analysis of ancient materials, due to its non-invasive and non-destructive analytical capabilities.

Air & Water Reactions

Flammable. Insoluble in water.

Reactivity Profile

Explosions have occurred when liquid air contacts organic matter. A cracked tube of activated charcoal immersed in liquid air exploded violently [J. Sci. Inst. 5:24 1928]. Zinc chlorate and charcoal (or finely divided organic material) form mixtures that may ignite or explode. Ignition or explosion may be caused by friction, percussion, or shock [U.S. Army Ordnance Safety Manual 1951].

Health Hazard

No significant symptoms

Fire Hazard

Special Hazards of Combustion Products: Incomplete combustion forms toxic carbon monoxide.

Safety Profile

Carbon itself has no toxic action, but it contains impurities that may be toxic. Fire hazard: reacts with liquid air, Ba(ClO3)2, BrFj, Cl0, Ca(ClO3)2, ClF2, F2, H2O2, Mg(ClO3)2, (O2 + wood), perchlorates, peroxides, (P + air), K + KClO3, mo3, Ru04, AgNO3, NaClO3, (AgCl + NaO2), S, (S + NaNO3), Zn(ClO3)2. Heats spontaneously, particularly when wet, freshly calcined, or tightly packed, and it can ignite and burn. Slight explosion hazard when exposed to heat or flame. To fight fire, use water, mist, foam, or dry chemical. When heated to decomposition it emits acrid smoke and fumes.

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.

Environmental Fate

Due to its large surface area, charcoal exerts its effects by absorbing a wide variety of drugs and chemicals. After the toxic substance attaches to the surface of the charcoal and because charcoal is not absorbed, it stays inside the GI tract, being eliminated in the feces along with the charcoal. In single-dose therapy, activated charcoal adsorbs the toxic substance ingested, and thus inhibits GI absorption and prevents or reduces toxicity.

Shipping

UN1362 Carbon, activated, Hazard Class: 4.2; Labels: 4.2-Spontaneously combustible material, International.

Toxicity evaluation

The presence of charcoal in a compound elevates the Koc value, resulting in reduction of mobility of compounds through the sediment and soil.Charcoal is stable under ambient environmental conditions.Hazardous short-term degradation products of charcoal are not likely.Charcoal and its products of degradation are not toxic. Special remarks on the products of biodegradation are not available.

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.
