style="font-family: 宋体;font-size: 14px">粉体真密度是粉体质量与其真体积之比值，其真体积不包括存在于粉体颗粒内部的封闭空洞。所以，测定粉体的真密度必须采用无孔材料、�/span></p><p><span style="font-family: 宋体;font-size: 14px">根据测定介质的不同，粉体真密度主要的测定方法可分为浸液法和气体置换法。浸液法是将粉末浸入於易润湿颗粒表面的浸液中，测定其所排除液体的体积。此法必须真空脱气以完全排除气泡。真空脱气操作可采用加热<span style="font-family:Times New Roman">(</span><span style="font-family:宋体">煮沸</span><span

14px">采用比重瓶测定粉体真密度是基于“阿基米得原理”的浸液法。将待测粉末浸入对其润湿而不溶解的浸液中，抽真空除气泡，求出粉末试样从已知容量的容器中排出已知密度的液体，就可计算所测粉末的真密度、�/span></p><p><span style="font-family: 宋体;font-size: 14px">气体置换法是用氦气代替浸润液，利用氦气是小分子直径惰性气体，具有易扩散、渗透性好、稳定性好的特点，迅速深入到材料的内部孔隙中，对常规方法无法测量的材料孔隙和不规则表面凹陷等均可迅速填充，测量出的样品体积与浸液法比较，会更加接近样品的真实体积，从而使得样品的真密度值更加贴近真实值。另外采用氦气“气体置换法”的真密度分析仪不会发生与材料反应的问题，不会对设备造成腐蚀，使用过程中安全系数高，且样品不会被污染可以直接回收，有利于贵重样品测试后的回收。采用这种方法的仪器操作更加简单，测试时间更短，测试结果准确，重复性更好，目前国内已有厂家生产，并已被纳入到部分行业的行业标准中、�/span></p><p><span
