【摘要】 设计了一种金属粉体导电特性的表征方法,以银粉为测试样本,采用堆砌体积电阻率表征粉体的导电特性。分别考察了填充量、测试负荷、测试稳定时间等因素对银粉堆砌体积电阻率的影响。结果表明当银粉填充量为4 g、测试负荷为800 g和测试稳定时间为30 min时,所得实验结果可以准确反映银粉的堆砌体积电阻率。更多还原

【Abstract】 A new characterization method of conductive fillers has been introduced in this paper via measuring the stacking volume resistivity of silver powders.The effects of the filling amount of silver powders,measuring load and measuring settling time on the stacking volume resistivity of silver powders were investigated.The results indicate that when the filling amount of silver powders is 4 g,the measuring load is 800 g and the measuring settling time is 30 minutes,the measuring date obtained can accurately reflect the stacking conductive characteristics of metal powders.更多还原
