摘要

In the current work, a device was proposed for the first time to deposit the panicles in situ on a transmission electron micrography grid within furnace aerosol reactors. The device was successfully tested on iron particles produced by thermal decomposition of Fe(CO)5 at 600 degreesC in a quartz tube heated by an electric heater. The particle depositions were made at four different spatial locations in the axial direction and investigated by transmission electron microscopy. At the reactor inlet, chain agglomerates of 2-3-nm particles were observed. At 19 cm from the inlet, the particles within the agglomerate structures fully coalesced by sintering, and at 32 cm (reactor outlet), polyhedral particles of about 100 nm in diameter emerged from the sintered body.
