Degussa possesses many years of experience in industrial flame
synthesis as well of fine powders as of nanomaterials.
Gas-phase-synthesis is a well-known chemical-manufacturing technique
for an extensive variety of nano-sized particles. Since the potential
of fine and especially nano-sized particles in high performance
applications has been identified, the scientific and commercial
interest has increased immensely, disclosing this field as a most
important technology of the future. The paper will present the basics
of the gas-phase-synthesis and particle formation process including
the relation between the principal process conditions and the product
characteristics.
The second part describes the synthesis and characterization of smart
inorganic nanocomposites. Isolated, magnetically decoupled
single-domain centers of nano-scaled iron oxide were embedded in an
amorphous silica matrix via flame synthesis providing
superparamagnetic behaviour. The iron oxide content of the composite
material, the size of the magnetic domains as of the composite
particles, the throughput and the precursor concentration were varied
systematically.
