Simultaneous data of the quasi-static compaction and electrical conductivity of porous, binary powder mixtures have been collected as a function of bulk density. The powder mixtures consist of a metal conductor, either titanium or iron, an insulator, and pores filled with ambient air. The data show a dependency of the conductivity in terms of relative bulk density and metal volume fraction on conductor type and conductor particle characteristics of size and shape. Finite element models using particle domains generated by discrete element method are used to simulate the bulk conductivity near its threshold while the general effective media equation is used to model the conductivity across the compression regime.

多孔二元粉末混合物的准静态压实和电导率的同时数据已被收集为堆积密度的函数。粉末混合物由金属导体（钛或铁）、绝缘体和充满环境空气的孔隙组成。数据显示在相对体积密度和金属体积分数方面的电导率对导体类型和导体颗粒尺寸和形状特征的依赖性。使用离散元方法生成的粒子域的有限元模型用于模拟接近其阈值的体电导率，而通用有效介质方程用于模拟整个压缩状态的电导率。
