An apparatus to synthesize ceramic nanoparticles with a precisely adjusted temperature history and a significant mass output.

摘要: For gas phase nanoparticle production, hot wall reactors are widely used. In this article, we will describe the fundamental design considerations for a reactor system able to produce oxide nanoparticles. The is outstanding in its ability mostly spherical nanoparticles at particle sizes of up 100 nm and even larger mass outputs order grams per hour by being rapidly quench aerosol. While high production rates or already easily obtained with reactors, it very challenging these particles rates. We show research that temperature number concentration major aspects influencing morphology end process. Investigation on performance setup shows good control over stability. A representative characterization using SEM scanning mobility sizer showed spherical, while size distribution had geometric standard deviation close 1.5. addition mentioned above, possibility manipulate aggregation downstream be presented as well. found applying electrical charges aerosol (in opposite polarity) can significantly foster aggregation.
