• 定義

  本品は、木材又は竹などを加熱することによって得られる乾燥した炭化物である。

• 解説

  ガラス状炭素ともいう．非晶質な組織をもち，熱膨張係数が小さいので熱変形が少なく，また熱容量も小さい．耐薬品性，耐食性，耐酸化性に優れる．緻密で優れた耐食性を示し，硬く，粒子の脱落がきわめて少ないことから，半導体製造プロセス部材，各種高温炉部材，結晶育成用るつぼ，電気化学装置部材などに使用される．

• 化粧品の成分用途

  不透明化剤、吸着剤、研磨.スクラブ剤、着色剤

• 説明

  The first use of charcoal comes from the black pigment used in European cave paintings around 32 000 years ago. It is possible that the earliest use of charcoal as a fuel in the smelting of copper began over 7000 years ago. The first definite evidence of human involvement with charcoal as a fuel goes back to 5500 years ago in the Middle East and Southern Europe, when the Egyptians, who were expert metal workers, discovered the smelting of iron using charcoal.

• 化学的特性

  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.

• 使用

  Charcoal has been used since the earliest times for several of purposes, including medicine and art, but by far its most important use has been as a metallurgical, cooking, industrial, and automotive fuel. Charcoal is used as a conventional fuel where an intense heat is wanted. Charcoal was also used historically as a source of carbon black in chemical reactions by grinding it up. In this form charcoal was a constituent of formulas for mixtures such as gunpowder and was important to early chemists. Due to its high surface area, charcoal can be used as a catalyst, a filter, or an adsorbent.

• 一般的な説明

  A black powder or granular mixed with a tar or starch and water binder pressed into regular lumps or briquettes. Heats slowly and ignites in air especially if wet.

• 空気と水の反応

  Flammable. Insoluble in water.

• 反応プロフィール

  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].

• 健康ハザード

  No significant symptoms

• 火災危険

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

• 安全性プロファイル

  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.

• 職業ばく露

  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.

• 環境運命予測

  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.

• 輸送方法

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

• 不和合性

  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.

• 廃棄物の処理

  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.
