Nanostructured materials condensation process

The CF-CVC (combustion flame-chemical vapor condensation) process developed by Kear and co-workers (Skandan et al., 1996 Tompa et al., 1999) is a continuous process using the equipment shown in Fig. 1. The starting materials are metal complexes that can be vaporized and fed into a flat flame, which immediately converts the compounds to nanostructured metal oxides. The particle dilution is controlled to prevent agglomeration in a hot state...

A number of processes are being used for producing nanomaterials for bulk production. The most common techniques used for synthesizing nanostructure materials include inert gas condensation, mechanical alloying, thermal spraying, electrodeposition, jet vapor deposition, vacuum thermal evaporation, and controlled chanical precipitation. 

There are several routes that can be chosen for the synthesis of nanostructured systems. The method may involve the preparation of novel compounds from a precursor that is called chemical synthesis or may involve only a vaporizatiOTi process and cooling the material under controlled condensation conditions it is classified as physical preparation.
