石墨是一種非金屬礦物質，具有耐高溫、抗腐蝕、抗熱震、強度大、韌性好、潤滑強度高、導熱、導電性能強等特有的物理化學性能，廣泛應用于冶金、機械、電子、化工、紡織、輕工、軍工、國防、航天、核能及耐火材料等行業，是當今高新技術發展必不可少的非金屬材料。

Graphite is a nonmetallic mineral with perfect high temperature resistance , rot resistance , thermal shock  resistance , extraordinary physical self-lubricity and electricity conductivity . It can be widely used in metallurgy , mechanism , electronics , chemical , textile , light industry , war industry, national defence , spaceflight , nuclearenergy and fireproof materials , so that graphite  has become a very important nonmetallic mineral nowadays.
