The measurement of electrical conductivity and the volumes of residual voids of 24 carbon blacks and their dry cathode mix blends with m-dinitrobenzene was standardized at a compression ratio of 10. The unique performance of Columbian P-1100-CL 20212 in magnesium A-cells is attributed to the rare optimization of these 2 properties. Comparative X-ray diffraction patterns of selected carbon blacks indicate a structural basis for the persistent resiliency of P-1100-CL 20212. Spectrographic evidence of the trace impurities of Al, V, Ni in the petroleum base Columbian P-1100 carbon blacks contrasts with the non-resilient spectroscopically pure acetylene base Shawinigan Black.
