Even if you manage to boil the earth into vapor, the vaporous earth would still remain gravitationally bound, the RMS velocity of silicon vapor being below the escape velocity of the mass of earth out to the edge of such an rock gas ball. This was worked out in the Thea collision model, where after the collision with Thea that formed the moon, the earth and Porto-moon was thought to have been encased by a single gravitationally bound, vigorously connecting rock vapor atmosphere that exchanged material between molten surfaces of earth and moon.
The grVitational binding energy of the mass of the earth, and moon, appears to be the threshold to overcome to completely obliterate all traces of the earth with solar energy, not the heat of vaporization of the material of the earth.
