石墨增碳劑是以煅燒石油焦為原料，將煅燒石油焦置于石墨化爐中，經過高溫石墨化，發生理化反應并除硫除灰分等雜質之后的產品。有時稱人造石墨增碳劑，用在增碳劑時，常被稱為超低硫/低氮增碳劑。石墨增碳劑的特點：黑色或暗灰色堅硬固體石油產品，帶有金屬光澤，增碳劑生產廠家呈多孔性，是由微小石墨結晶形成(cheng)(cheng)粒狀(zhuang)、柱狀(zhuang)或針狀(zhuang)構成(cheng)(cheng)的(de)(de)(de)炭(tan)體物。石油(you)焦組分是碳(tan)氫化(hua)(hua)合物，含碳(tan)99%以上，還(huan)含有氮、氯(lv)、硫及重金(jin)屬化(hua)(hua)合物。石墨增碳(tan)劑(ji)(ji)在工(gong)(gong)業(ye)上用(yong)途很廣，主要用(yong)于冶金(jin)、鑄(zhu)造(zao)、精密鑄(zhu)造(zao)中；煅燒增碳(tan)劑(ji)(ji)用(yong)于制作冶煉上的(de)(de)(de)高溫坩堝、機械工(gong)(gong)業(ye)的(de)(de)(de)潤滑(hua)劑(ji)(ji)、制作電(dian)極(ji)和鉛筆芯；廣泛(fan)用(yong)于冶金(jin)工(gong)(gong)業(ye)的(de)(de)(de)高級耐火(huo)材(cai)料與涂料、軍事工(gong)(gong)業(ye)火(huo)工(gong)(gong)材(cai)料安定劑(ji)(ji)、輕工(gong)(gong)業(ye)的(de)(de)(de)鉛筆芯、電(dian)氣工(gong)(gong)業(ye)的(de)(de)(de)碳(tan)刷、電(dian)池工(gong)(gong)業(ye)的(de)(de)(de)電(dian)極(ji)、化(hua)(hua)肥工(gong)(gong)業(ye)催化(hua)(hua)劑(ji)(ji)等。
