The incongruent evaporation behavior of troilite in the primordial solar nebula is discussed. The evaporation kinetics of troilite and metallic iron is applied to the evaporation of dust particles which fall toward the protosun in the turbulent primordial solar nebula using a recent dynamic model for the adiabatic nebula. Calculations were carried out for dust particles which fall both along the mid-plane and the surface. It was found in both cases that evaporation of iron and troilite particles would occur almost under equilibrium conditions, although troilite particles could survive in the inner reigon better than predicted by equilibrium calculations due to the effects of evaporation kinetics.
