Ultrafine particle of indium trioxide have been produced by evaporating indium granule from a nichrome boat in the electric fiield. Two electric plates (4cm×4cm, 1.5cm apart) were placed just above the evaporation source. Shape of smoke changed drastically by the applied voltage between 0〜300V. It was found that the particle size can be controlled by the applied voltage.
