土狀石墨:又稱微晶石墨，也叫非晶質(zhì)石墨或隱晶質(zhì)石墨（又名黑鉛粉）,這種石墨的晶體直徑一般小于1微米，只有在電子顯微鏡下才能見到晶形。顏色剛灰，有金屬光澤，質(zhì)軟，莫氏硬度1-2，比重2-2.24，化學(xué)性質(zhì)穩(wěn)定，不受強(qiáng)酸堿影響，有害雜質(zhì)少，鐵，硫，磷，氮，鉬，氫含量低，具有耐高溫、耐腐蝕、耐酸堿、抗氧化、可塑性、潤滑性、導(dǎo)熱性、導(dǎo)電性等一系列優(yōu)質(zhì)特性，廣泛用于鑄造、涂抹、電池、碳素制品、鉛筆、顏料、焊條、石墨乳劑、脫硫劑、防腐劑、潤滑劑、冶煉增碳劑、注定保護(hù)渣及各種耐火材料。
Earthy graphite: also known as microcrystalline graphite, also called amorphous graphite or aphanitic graphite (also known as black lead powder).Generally it is crystal is less than 1 micron in diameter, and only can be seen through the electron microscope.
With gray color, metallic luster, soft, Mohs hardness of 1-2,the proportion of 2-2.24 and chemically stable, free from strong acid-base effort. It has harmful impurities and with less iron
、sulfur、phosphorus、nitrogen、molybdenum and hydrogen. Besides it can resist high temperature, corrosion, acid and antioxidant, meanwhile having good plasticity, lubrication, thermal conductivity and electrical conductivity. It is being widely used in casting, painting, batteries, carbon products, pencils, paint ,welding rod ,graphite emulsion, desulfurization agents, preservations, lubricants, refining carburant, destined flux and all kinds of refractory materials.
