三、石墨粉價格多少錢一噸

石墨粉是一種礦物粉末，主要成分為碳單質，質軟，黑灰色，常溫下化學性質穩定，不溶于水、稀酸、稀堿和有機溶劑，具有耐高溫導電性能，可用作耐火材料、導電材料、潤滑材料、高溫冶金材料、磨光劑和防銹劑等，是一種應用廣泛的化工原料。石墨粉的種類眾多，不同種類的石墨粉用途不同，價格也有所不同，具體價格并不是統一的，要看石墨粉的含碳量、粒度等參數要求，一般市面上的石墨粉在一千多元每噸到幾萬元每噸甚至幾十萬元每噸都有。購買石墨粉時，可以通過看外觀、將石墨粉放入水中、煅燒石墨粉等方法來判斷石墨粉的質量好壞。如果您需要購買石墨粉，可以先來了解一下石墨十大品牌。

四、石墨電極的用途和性能

石(shi)墨(mo)電(dian)(dian)(dian)(dian)極是(shi)一種耐高溫石(shi)墨(mo)質導電(dian)(dian)(dian)(dian)材料(liao)(liao)，是(shi)在電(dian)(dian)(dian)(dian)弧爐(lu)中以電(dian)(dian)(dian)(dian)弧形式釋放電(dian)(dian)(dian)(dian)能(neng)對爐(lu)料(liao)(liao)進行加(jia)(jia)熱(re)熔化的(de)導體，它主(zhu)要用(yong)于(yu)電(dian)(dian)(dian)(dian)弧煉鋼爐(lu)、礦熱(re)電(dian)(dian)(dian)(dian)爐(lu)、電(dian)(dian)(dian)(dian)阻爐(lu)等(deng)領域(yu)，利用(yong)石(shi)墨(mo)電(dian)(dian)(dian)(dian)極向爐(lu)內導入電(dian)(dian)(dian)(dian)流，利用(yong)電(dian)(dian)(dian)(dian)極端(duan)部和(he)爐(lu)料(liao)(liao)之間引發(fa)電(dian)(dian)(dian)(dian)弧所產生的(de)高溫熱(re)源來(lai)(lai)進行冶煉，還(huan)可以用(yong)來(lai)(lai)制(zhi)備異型石(shi)墨(mo)產品。石(shi)墨(mo)電(dian)(dian)(dian)(dian)極具(ju)有較強的(de)導電(dian)(dian)(dian)(dian)性(xing)、導熱(re)性(xing)，較高的(de)抗熱(re)振(zhen)性(xing)能(neng)和(he)化學穩定性(xing)能(neng)，良好的(de)潤滑性(xing)和(he)抗磨(mo)性(xing)，且加(jia)(jia)工較容易、比重(zhong)小、加(jia)(jia)工速(su)度快，因此應用(yong)廣(guang)泛。
