导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)石(shi)墨是(shi)一种高(gao)导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)性能(neng)的材料，通(tong)(tong)常用(yong)(yong)来制作具(ju)有导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)性的石(shi)墨制品等。导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)炭黑(hei)是(shi)具(ju)有低电(dian)(dian)(dian)(dian)(dian)(dian)阻或高(gao)电(dian)(dian)(dian)(dian)(dian)(dian)阻性能(neng)的炭黑(hei)。可赋予制品导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)作用(yong)(yong)。其特点为粒径小，比(bi)表面积大(da)且(qie)粗糙(cao)，结构高(gao)，表面洁净(化合(he)物(wu)(wu)少(shao))等。导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)体是(shi)容(rong)易导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)的物(wu)(wu)体，即是(shi)能(neng)够让电(dian)(dian)(dian)(dian)(dian)(dian)流通(tong)(tong)过材料；不容(rong)易导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)的物(wu)(wu)体叫绝缘体。（并(bing)不是(shi)能(neng)导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)的物(wu)(wu)体叫导(dao)(dao)(dao)体，不能(neng)导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)的物(wu)(wu)体叫绝缘体，这是(shi)一般人常犯(fan)的错(cuo)误(wu)）金属导(dao)(dao)(dao)体里面有自由运动的电(dian)(dian)(dian)(dian)(dian)(dian)子(zi),导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)的原因是(shi)自由电(dian)(dian)(dian)(dian)(dian)(dian)子(zi).半(ban)导(dao)(dao)(dao)体随温度其电(dian)(dian)(dian)(dian)(dian)(dian)阻率逐(zhu)渐(jian)变小,导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)性能(neng)大(da)大(da)提高(gao),导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)原因是(shi)半(ban)导(dao)(dao)(dao)体内的空(kong)穴和电(dian)(dian)(dian)(dian)(dian)(dian)子(zi)对。在科(ke)学及工(gong)程上(shang)常用(yong)(yong)利用(yong)(yong)欧姆来定义某一材料的导(dao)(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)程度。

石(shi)(shi)墨是(shi)导(dao)体(ti)(ti),能(neng)导(dao)电(dian)。碳(tan)中的(de)石(shi)(shi)墨属于(yu)导(dao)体(ti)(ti),石(shi)(shi)墨环石(shi)(shi)墨是(shi)元素(su)碳(tan)的(de)一种同素(su)异形体(ti)(ti),每个(ge)碳(tan)原(yuan)子(zi)(zi)的(de)周边(bian)(bian)连结著另外三个(ge)碳(tan)原(yuan)子(zi)(zi)(排列(lie)方(fang)式呈(cheng)蜂巢式的(de)多(duo)个(ge)六边(bian)(bian)形)以共(gong)价键(jian)结合(he),构(gou)成(cheng)共(gong)价分子(zi)(zi)，由(you)(you)于(yu)每个(ge)碳(tan)原(yuan)子(zi)(zi)均会放出一个(ge)电(dian)子(zi)(zi),那(nei)些电(dian)子(zi)(zi)能(neng)够自(zi)由(you)(you)移动,因此石(shi)(shi)墨属于(yu)导(dao)体(ti)(ti)，而(er)金(jin)刚石(shi)(shi)就是(shi)绝缘体(ti)(ti)了。
