It is a native element mineral found in metamophic and igneous rocks. 石墨是一种极端的矿物. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity. 与此形成鲜明对比的是, it is extremely resistant to heat and nearly inert in contact with almost any other material. These extreme properties give it a wide range of uses in metallurgy and manufacturing.<\/p><\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ t \ \ t<\/div>\ n \ t \ t \ \ t
