Abstract

A vaporizer apparatus efficiently vaporizes difficult-to-vaporize materials such as complex feed materials for producing a high dielectric or ferroelectric material. The vaporizer apparatus includes a vaporizing passage formed by a pair of opposed walls separated by a minute spacing to a liquid feed entrance provided at one end of the vaporizing passage, a vaporized feed exit provided at an opposite end of the vaporizing passage, and a heating arrangement for heating the walls to a temperature in excess of a vaporizing temperature of the liquid feed so that the liquid feed material may be guided into the vaporizing passage to be vaporized.
