The apparatus contains a vertical evaporator element which has an internal heating unit and an apparatus for introducing a regulated amount of the liquid iron compound onto the surface of the evaporator element. The evaporator element being enclosed in a gas tight housing into which a purge gas may be introduced to carry the resultant vapors out of the housing to a reactor chamber. Also disclosed is a method for evaporating a liquid iron compound comprising placing the liquid iron compound onto the surface of the heated evaporator element, thereby causing the iron compound to vaporize and then carrying the vaporized iron compound out of the evaporator with a purge gas. Further disclosed is a method for forming iron oxide using the evaporator.
