Nanopowders-CCVC Process
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.
