石墨具有導電性好、耐高溫、耐酸、耐堿腐蝕、易加工等優點。石墨制品加(jia)工是指經過特定的(de)工藝和(he)(he)辦法，將原(yuan)資料和(he)(he)半廢品轉化為目的(de)請求的(de)過程。石墨是軟的(de)，黑灰色的(de)，油膩的(de)。硬(ying)度(du)(du)為1-2。隨著雜質的(de)增加(jia)，硬(ying)度(du)(du)沿垂(chui)直方向增加(jia)到(dao)3-5。因而，它(ta)被普遍應用于冶金、化工、電化學等行業。

石(shi)(shi)墨(mo)電(dian)(dian)(dian)(dian)(dian)極(ji)是采(cai)用(yong)(yong)石(shi)(shi)油(you)焦、針(zhen)狀焦為(wei)骨料(liao)(liao)(liao)，煤瀝青為(wei)粘結劑，經過混捏、成 型、焙燒、浸漬(zi)、石(shi)(shi)墨(mo)化、機械加工(gong)等一(yi) 系列(lie)工(gong)藝(yi)過程(cheng)消費出來的(de)(de)(de)一(yi)種耐高溫(wen)石(shi)(shi)墨(mo)質導(dao)電(dian)(dian)(dian)(dian)(dian)資(zi)料(liao)(liao)(liao)。石(shi)(shi)墨(mo)電(dian)(dian)(dian)(dian)(dian)極(ji)是電(dian)(dian)(dian)(dian)(dian)爐(lu)(lu)煉(lian)(lian)鋼(gang)的(de)(de)(de)重要高溫(wen)導(dao)電(dian)(dian)(dian)(dian)(dian)資(zi)料(liao)(liao)(liao)，經過石(shi)(shi)墨(mo)電(dian)(dian)(dian)(dian)(dian)極(ji)向(xiang)電(dian)(dian)(dian)(dian)(dian)爐(lu)(lu)輸入(ru)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)，應用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)極(ji)端部和爐(lu)(lu)料(liao)(liao)(liao)之間引發電(dian)(dian)(dian)(dian)(dian)弧(hu)產(chan)生的(de)(de)(de)高溫(wen)作為(wei)熱源，使爐(lu)(lu)料(liao)(liao)(liao)凝結停止(zhi)煉(lian)(lian)鋼(gang)。其(qi)他(ta)(ta)一(yi)些冶煉(lian)(lian)黃(huang)磷(lin)、工(gong)業硅(gui)、磨料(liao)(liao)(liao)等資(zi)料(liao)(liao)(liao)的(de)(de)(de)礦熱爐(lu)(lu)也用(yong)(yong)石(shi)(shi)墨(mo)電(dian)(dian)(dian)(dian)(dian)極(ji)作為(wei)導(dao)電(dian)(dian)(dian)(dian)(dian)資(zi)料(liao)(liao)(liao)。應用(yong)(yong)石(shi)(shi)墨(mo)電(dian)(dian)(dian)(dian)(dian)極(ji)*而特殊的(de)(de)(de)物理化學性能(neng)(neng)，在其(qi)他(ta)(ta)工(gong)業部門也有普遍的(de)(de)(de)用(yong)(yong)處。
