1bitgraphite=石墨（graphite）
石墨（graphite）是一种结晶形碳。六方晶系,为铁墨色至深灰色。密度2.25克/厘米3,硬度1.5,溶点3652℃,沸点4827℃。质软,有滑腻感,可导电。化学性质不活泼,耐腐蚀,与酸、碱等不易反应。在空气或氧气中加强热,可燃烧并生成二氧化碳。强氧化剂会将它氧化成有机酸。用作抗摩剂和润滑材料,制作坩埚、电极、干电池、铅笔芯。高纯度石墨可在核反应堆上作中子减速剂。常被称为炭精或黑铅,因为以前被误认为是铅。Graphite is a crystalline form of carbon (graphite). Hexagonal system, for the ink to dark grey iron. Density of 2.25 g/cm 3, 1.5 hardness, melting point 3652 ℃, boiling point of 4827 ℃. Soft, creamy feeling, can conduct electricity. Chemically inert, corrosion resistance, not easy reaction with acid, alkali, etc. Strengthen the heat in the air or oxygen, can burn and produce carbon dioxide. Strong oxidizer it will be oxidized to organic acids. Used as antifriction agent and lubrication materials, production of crucible, electrodes, batteries, pencil lead. High purity graphite can be made on the nuclear reactor neutron moderator. Is often referred to as carbon or graphite, because used to be mistaken for lead.
