Abstract
An aerosol delivery apparatus is used to deliver an aerosol into a reaction chamber for chemical reaction to produce reaction products such as nanoparticles. A variety of improved aerosol delivery approaches provide for the production of more uniform reaction products. In preferred embodiments, a reaction chamber is used that has a cross section perpendicular to the flow of reactant having a dimension along a major axis greater than a dimension along a minor axis. The aerosol preferably is elongated along the major axis of the reaction chamber.
Claims20
A method of producing particles, the method comprising introducing a reactant stream into a reaction chamber, the reactant stream intersecting a radiation beam, the reactant stream comprising an aerosol, a vapor metal and a compound that absorbs sufficient radiation energy to drive a reaction resulting in particle formation, wherein the aerosol is generated with an aerosol generator.
A method of producing particles, the method comprising introducing a reactant stream into a reaction chamber, the reactant stream intersecting a radiation beam path, the reactant stream comprising a vapor and an aerosol comprising a metal reactant wherein the vapor forms a vapor stream in a delivery tube oriented directly into the reaction chamber and wherein the aerosol flows into the vapor stream from a direction that is not oriented toward the reaction chamber.
