New flame process for producing nanopowders

As the market for nanophase powders has grown rapidly, a number of nanopowder processing technologies have also evolved over the past two decade. A low-pressure chemical vapor condensation (CVC) process has been developed, leading to large-scale production. In the combustion flame-CVC (CF-CVC) process, a stable flat flame is generated by burning a fuel/oxygen mixture at low pressure. Chemical precursors, introduced along with combustible, experience rapid thermal decomposition in the hot zone of the flame. A key to the successful development of the CF-CVC process is detailed prior modeling not only of the combustion region but also the whole assembly.
