由于石墨具有許多優良的性能，因此在冶金、化工、電氣、機械、紡織、國防等工業部門獲得廣泛應用。可以是石墨坩堝，石(shi)墨(mo)(mo)(mo)棒，石(shi)墨(mo)(mo)(mo)模(mo)具等(deng)等(deng)各(ge)種制品，石(shi)墨(mo)(mo)(mo)的一個主(zhu)要(yao)用(yong)(yong)途就是生產耐(nai)(nai)(nai)火(huo)材(cai)(cai)料(liao)(liao)，包括耐(nai)(nai)(nai)火(huo)磚(zhuan)(zhuan)，坩堝，連(lian)續鑄(zhu)(zhu)造(zao)粉，鑄(zhu)(zhu)模(mo)芯，鑄(zhu)(zhu)模(mo)洗(xi)滌劑(ji)和(he)耐(nai)(nai)(nai)高溫材(cai)(cai)料(liao)(liao)。近年來，耐(nai)(nai)(nai)火(huo)材(cai)(cai)料(liao)(liao)工(gong)業(ye)中(zhong)兩個重要(yao)的變化(hua)是鎂碳(tan)磚(zhuan)(zhuan)在煉鋼(gang)爐內襯(chen)中(zhong)被(bei)廣泛應(ying)用(yong)(yong)，以及率碳(tan)磚(zhuan)(zhuan)在連(lian)續鑄(zhu)(zhu)造(zao)中(zhong)的應(ying)用(yong)(yong)，使(shi)石(shi)墨(mo)(mo)(mo)耐(nai)(nai)(nai)火(huo)材(cai)(cai)料(liao)(liao)與煉鋼(gang)業(ye)精(jing)密(mi)相連(lian)，全(quan)*煉鋼(gang)業(ye)約消耗的耐(nai)(nai)(nai)火(huo)材(cai)(cai)料(liao)(liao)。

潤(run)滑(hua)油往往不能(neng)在(zai)高速、高溫、高壓的條件下使(shi)用，而石(shi)(shi)墨耐磨材(cai)(cai)料可以在(zai)-溫度并在(zai)很(hen)高的滑(hua)動(dong)速度下(/)不用潤(run)滑(hua)油工(gong)作。許(xu)多輸(shu)送(song)腐蝕介質(zhi)的設備，廣泛采用石(shi)(shi)墨材(cai)(cai)料制成活塞環、密封圈(quan)和軸承，它們運(yun)轉(zhuan)時(shi)，勿需加入潤(run)滑(hua)油，石(shi)(shi)墨乳也是許(xu)多金屬(shu)加工(gong)(拔絲、拉管)時(shi)的良好的潤(run)滑(hua)劑。

石(shi)墨和其他雜質材料用(yong)于煉鋼工業時(shi)可作(zuo)為(wei)增碳(tan)(tan)劑。滲碳(tan)(tan)使用(yong)的(de)碳(tan)(tan)質材料的(de)范(fan)圍。

石(shi)墨(mo)(mo)(mo)生產新工藝新技(ji)術很廣，包括人造石(shi)墨(mo)(mo)(mo)、石(shi)油焦(jiao)、冶金焦(jiao)炭和天然石(shi)墨(mo)(mo)(mo)。在*范圍內煉鋼增碳(tan)劑用(yong)石(shi)墨(mo)(mo)(mo)仍是土狀石(shi)墨(mo)(mo)(mo)的主要用(yong)途(tu)之一。

石墨在電(dian)(dian)(dian)(dian)(dian)氣工業中廣泛用(yong)來作電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)、電(dian)(dian)(dian)(dian)(dian)刷、碳棒、碳管、水銀整流器的(de)正極(ji)(ji)、石墨墊圈(quan)、電(dian)(dian)(dian)(dian)(dian)話*件、電(dian)(dian)(dian)(dian)(dian)視(shi)機顯(xian)像管的(de)涂(tu)層等(deng)等(deng)。其中以石墨電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)應用(yong)較廣，在冶煉各種合金鋼、鐵合金時(shi)，使(shi)用(yong)石墨電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)，這時(shi)強大的(de)電(dian)(dian)(dian)(dian)(dian)流通過電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)導入電(dian)(dian)(dian)(dian)(dian)爐的(de)熔煉區，產生電(dian)(dian)(dian)(dian)(dian)弧，使(shi)電(dian)(dian)(dian)(dian)(dian)能轉化為熱能，溫度升高到(dao)左(zuo)右(you)，從而達到(dao)熔煉或反應的(de)目(mu)的(de)。此(ci)外(wai)，在電(dian)(dian)(dian)(dian)(dian)解金屬鎂(mei)、鋁、鈉時(shi)，電(dian)(dian)(dian)(dian)(dian)解槽的(de)陽極(ji)(ji)也(ye)用(yong)石墨電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。生產剛砂的(de)電(dian)(dian)(dian)(dian)(dian)阻爐也(ye)用(yong)石墨電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)作爐頭(tou)導電(dian)(dian)(dian)(dian)(dian)材料。

石(shi)墨具有良(liang)好的化學穩定性。經(jing)過特殊加工的石(shi)墨，具有耐腐(fu)蝕、導熱性好、滲透率(lv)低等特點，而廣泛用于制作熱交(jiao)換(huan)器、反(fan)應槽、凝縮器、燃燒塔(ta)、吸收塔(ta)、冷卻器、加熱器、過濾器、泵等設(she)備。這些設(she)備用于石(shi)油化工、濕法(fa)冶(ye)金、酸(suan)堿生產、合成纖(xian)維、造紙等工業部門，可節省(sheng)大量(liang)的金屬材料。

電(dian)氣工業(ye)中所(suo)(suo)使用的石墨(mo)(mo)，對粒(li)(li)度(du)和品位(wei)要(yao)(yao)求(qiu)(qiu)很高。如堿性蓄電(dian)池和一些特殊(shu)的電(dian)碳制品，要(yao)(yao)求(qiu)(qiu)石墨(mo)(mo)粒(li)(li)度(du)控制在目目范圍(wei)內，品位(wei)以(yi)上(shang)，有害雜(za)質(主要(yao)(yao)是金屬鐵)要(yao)(yao)求(qiu)(qiu)在以(yi)下。電(dian)視機顯像管所(suo)(suo)用的石墨(mo)(mo)，粒(li)(li)度(du)要(yao)(yao)求(qiu)(qiu)在以(yi)下。作(zuo)耐磨和潤滑材料石墨(mo)(mo)在機械工業(ye)中常作(zuo)潤滑劑。
