The low densitygraphite gets higher friction coefficient and bulk worn loss than the highdensitygraphite.
低密度石墨的摩擦系数和体积磨损量比高密度石墨材料高。

Carbon materials, including graphite, carbon fibre, carbon foam and expanded graphite possess the properties of high conductivity, low density and good chemical stability.
碳材料如石墨、碳纤维、碳泡沫和膨胀石墨，他们都具有高导热系数、低密度和良好的化学稳定性。

The real density of needle coke strongly influences the bulk density of graphite electrodes: a coke of high real density tends to yield low density rods.
