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(shi)墨(mo)結晶形成粒狀、柱(zhu)狀或(huo)針(zhen)狀構成的(de)炭體(ti)物(wu)。石(shi)油(you)焦組(zu)分(fen)是碳(tan)(tan)(tan)氫化合(he)物(wu)，含碳(tan)(tan)(tan)99%以上，還含有氮(dan)、氯(lv)、硫及(ji)重(zhong)金屬化合(he)物(wu)。石(shi)墨(mo)增(zeng)碳(tan)(tan)(tan)劑(ji)在工(gong)(gong)(gong)業(ye)(ye)(ye)上用途很廣(guang)，主要用于冶金、鑄造(zao)、精密鑄造(zao)中(zhong)；煅燒增(zeng)碳(tan)(tan)(tan)劑(ji)用于制(zhi)作冶煉上的(de)高(gao)溫坩堝、機械(xie)工(gong)(gong)(gong)業(ye)(ye)(ye)的(de)潤(run)滑劑(ji)、制(zhi)作電極和鉛筆(bi)芯；廣(guang)泛用于冶金工(gong)(gong)(gong)業(ye)(ye)(ye)的(de)高(gao)級耐火材(cai)料(liao)與涂料(liao)、軍(jun)事工(gong)(gong)(gong)業(ye)(ye)(ye)火工(gong)(gong)(gong)材(cai)料(liao)安定劑(ji)、輕(qing)工(gong)(gong)(gong)業(ye)(ye)(ye)的(de)鉛筆(bi)芯、電氣工(gong)(gong)(gong)業(ye)(ye)(ye)的(de)碳(tan)(tan)(tan)刷、電池工(gong)(gong)(gong)業(ye)(ye)(ye)的(de)電極、化肥工(gong)(gong)(gong)業(ye)(ye)(ye)催化劑(ji)等。
