Abstract
An aerosol generator for producing fine droplets in large quantities is used in an apparatus which can produce small particles having a high degree of crystallization and large surface area. The aerosol generator includes a chamber having a porous filter and a solution, and air is supplied to an upper side of the filter. A low pressure driving force, such as by a vacuum, is supplied to the chamber below the filter to generate droplets. A pyrogenetic reactor dries and pyrolyzes the droplets produced by the aerosol generator to give ultrafine particles and an ultrafine particle collector collects the ultrafine particles obtained by the pyrogenetic reactor. The low pressure driving force moves the droplets through the pyroletic reactor.
