font-size: 16px;">1) 耐高温性：石墨的熔点为3850±50℃，沸点�?250℃，即使经超高温电弧灼烧，重量的损失很小，热膨胀系数也很小。石墨强度随温度提高而加强，�?000℃时，石墨强度提高一倍、�br style="margin: 0px; padding: 0px;"/><br style="margin: 0px; padding: 0px;"/>2) 导电、导热性：石墨的导电性比一般非金属矿高一百倍。导热性超过钢、铁、铅等金属材料。导热系数随温度升高而降低，甚至在极高的温度下，石墨成绝热体。石墨能够导电是因为石墨中每个碳原子与其他碳原子只形�?个共价键,每个碳原子仍然保�?个自由电子来传输电荷、�br style="margin: 0px;
