Abstract
In the preparation of fine particles of metal sulfide such as zinc sulfide and cadmium sulfide using the spray pyrolysis method, the electrostatic spray method was applied to atomize the starting solutions. The optimum operation conditions where the droplets could be generated from a Taylor cone were examined experimentally. It was shown that the use of the electrostatic spray pyrolysis method is available for preparing the several dozens nanometer-sized fine particles, in comparison with a typical ultrasonic spray pyrolysis method that produced the several hundreds nanometer size.
