1.1 Manufacturing Device and Aerosol-Phase Development

(Fumed Alumina)

Fumed alumina, likewise known as pyrogenic alumina, is a high-purity, nanostructured type of light weight aluminum oxide (Al two O FIVE) generated via a high-temperature vapor-phase synthesis procedure.

Unlike traditionally calcined or sped up aluminas, fumed alumina is generated in a fire activator where aluminum-containing forerunners– generally aluminum chloride (AlCl ₃) or organoaluminum substances– are ignited in a hydrogen-oxygen flame at temperatures exceeding 1500 ° C.

In this severe environment, the precursor volatilizes and undergoes hydrolysis or oxidation to create aluminum oxide vapor, which swiftly nucleates right into main nanoparticles as the gas cools down.

These nascent bits clash and fuse together in the gas phase, forming chain-like aggregates held together by strong covalent bonds, leading to a very permeable, three-dimensional network structure.
