1.1 Manufacturing Device and Aerosol-Phase Formation

(Fumed Alumina)

Fumed alumina, additionally called pyrogenic alumina, is a high-purity, nanostructured form of light weight aluminum oxide (Al two O THREE) produced with a high-temperature vapor-phase synthesis process.

Unlike conventionally calcined or sped up aluminas, fumed alumina is created in a flame reactor where aluminum-containing precursors– normally aluminum chloride (AlCl ₃) or organoaluminum substances– are ignited in a hydrogen-oxygen fire at temperatures surpassing 1500 ° C.

In this severe environment, the precursor volatilizes and undergoes hydrolysis or oxidation to develop light weight aluminum oxide vapor, which quickly nucleates into primary nanoparticles as the gas cools.

These incipient particles clash and fuse with each other in the gas phase, forming chain-like accumulations held with each other by strong covalent bonds, causing an extremely porous, three-dimensional network structure.
