1.1 Production Mechanism and Aerosol-Phase Formation

(Fumed Alumina)

Fumed alumina, also referred to as pyrogenic alumina, is a high-purity, nanostructured type of light weight aluminum oxide (Al ₂ O FIVE) produced through a high-temperature vapor-phase synthesis procedure.

Unlike conventionally calcined or precipitated aluminas, fumed alumina is generated in a flame reactor where aluminum-containing forerunners– typically light weight aluminum chloride (AlCl five) or organoaluminum compounds– are combusted in a hydrogen-oxygen flame at temperature levels exceeding 1500 ° C.

In this extreme environment, the forerunner volatilizes and goes through hydrolysis or oxidation to form aluminum oxide vapor, which quickly nucleates right into key nanoparticles as the gas cools down.
