…In 1896, American EG Acheson investigated a furnace used to manufacture silicon carbide (SiC), and discovered that SiC decomposed and produced graphite in the hottest part of the furnace. This led him to think of producing artificial graphite using an electric arc furnace. For this reason, artificial graphite is also called Acheson graphite. There are different manufacturing methods depending on the application, but to make molded products, the raw carbon material (amorphous carbon such as coke, anthracite, and carbon black) is crushed and sieved. … *Some of the terminology explanations that mention "Acheson graphite" are listed below.

…アメリカのE.G.アチソンは,1896年に炭化ケイ素SiC製造用の炉を調べたところ,炉内の最高温度になる部位にSiCが分解して黒鉛が生成していることを発見,アーク炉により人造黒鉛を製造することを考えた。このため人造黒鉛をアチソン黒鉛ともいう。用途に応じた製法があるが,成形品をつくるには,原料の炭素材料(コークス,無煙炭,カーボンブラックなどの無定形炭素)を粉砕,ふるい分けする。… ※「アチソン黒鉛」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
