Is the inner core solid, liquid, or gas? what keeps it in the phase?

The temperature in the inner core can easily melt both iron and nickel but, because of too much pressure, the particles of iron and nickel are being compressed no to be able to do phase changes to turn into liquid. Too much pressure in the inner core keeps it in a solid phase and having a very high density
