METHOD FOR THE MANUFACTURE OF INORGANIC NANOPARTICLES IN AIR AND DEVICE THEREFOR |
摘要 |
<p>Provided are a method and a device for producing nanoparticles of a low melting point material such as gold at more than 10 times faster the rate of conventional technology while maintaining the time-averaged temperature of pulse-modulated atmospheric-pressure plasma at a temperature that is low enough so as not to damage a heat-sensitive material disposed downstream. This method of preparing nanoparticles of a low melting point inorganic material in which a wire made of a low melting point inorganic material is inserted into a plasma-generating capillary tube or a plasma-generating nozzle and atmospheric-pressure high frequency plasma is generated in the capillary tube or nozzle is characterized by generating the plasma by applying a high frequency voltage possessing a waveform which exhibits its maximum value when it rises and then immediately falls, and which is pulse-modulated so that the duty ratio thereof is 10% or less.</p> |
