| Summary: | cules. By increasing the pressure, the number of dissociated molecules (and thus of the protonic carriers) increase exponentially across the molecular-ionic cross-over. In the ionic regime all the protons contribute equal-ly to the conductivity, and a further increase in pressure increases the proton mobility without changing the number of carriers. Moving deeper into the planet, the ice core boundary is met at 600 GPa and 7000 K according to the presently accepted planetary isentrope (2). At these conditions we predict water and ammonia to be metallic (24). This may have at least two consequences. First, the dynamo generation of the magnetic field |
