nGimat's NanoSpraySM Combustion
Processing technology is a platform technology that relies on
the proprietary Nanomiser®
Device to produce aerosols with controllable droplet size
distribution. In Combustion Chemical Vapor Condensation (CCVC)
production of nanopowders, the NanoSpray Combustion Processing
technology is used to convert a starting liquid solution containing
chemical precursors into an ultra-fine aerosol that is efficiently
combusted to produce nanopowders, which are collected in a bag
house. Ultra-fine atomization with the Nanomiser Device enables the
use of any soluble precursor without concern for its vapor pressure.
By adjusting solution concentrations and constituents, a wide range
of compounds can be formed quickly and easily. In a production
environment, the technology enables economical large-scale
production of nanopowders because it takes advantage of inexpensive
and environmentally friendly precursors dissolved in solvents that
also act as the combustible fuel.

nGimat's NanoSpray Combustion Processing technology provides a new
and highly competitive way to produce multi-component nanopowders at
reduced cost. The capability and versatility of the process have
already been proven in the synthesis of a variety of materials. The
key advantages of this technology are:
- Ability to produce complex multi-component materials by simply
adjusting the solution chemistry, thereby enabling rapid
prototyping and reduced time to market;
- Control of size, shape, and morphology of nanopowders produced
from sub-micron droplets;
- Inherent scalability of liquid spray flame process. As a
result, capital and ongoing operating costs of this process can be
significantly reduced compared to other methods for nanoparticle
synthesis; and
- Use of inexpensive, environmentally friendly, soluble chemical
reagents.
