石墨是一种非金属矿物质，具有耐高温、抗腐蚀、抗热震、强度大、韧性好、润滑强度高、导热、导电性能强等特有的物理化学性能，广泛应用于冶金、机械、电子、化工、纺织、轻工、军工、国防、航天、核能及耐火材料等行业，是当今高新技术发展必不可少的非金属材料。

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.
