Conductive Carbon Black

Conductive carbon black - it's carbon, not soot

To be fair, conductive carbon black does look very like soot. The reason why carbon black has massively higher conductive properties is because it also has a massively higher surface-to-volume-ratio. In simple terms, soot is much denser than carbon black. Because of this, it takes much longer for any stimulus to have an effect on it. In addition to its density, there are significant chemical differences between carbon black and soot. For example, it's actually quite common for there to be less than 60% actual carbon in soot, with the rest of the substance being made up largely of ash, in some cases over half of soot is actually ash.
