CCVD - Combustion Chemical Vapour Deposition

In the process of Combustion Chemical Vapor Deposition, often also referred to as flame pyrolysis, special precursors are introduced into a fuel gas-air mixture and chemically converted in the flames of a burner specially optimized for the coating (pyrolysis). Propane or natural gas (methane) as well as air are used as standard and mixed in an approximately stoichiometric ratio. In principle, other fuel gases (e.g. hydrogen or acetylene) and a higher proportion of oxygen than in normal air are also possible in order to control the flame temperature and thus the chemical reactivity of the flames.

Depending on the substrate material and the aim of surface functionalization, the type and state of the precursor, the fuel gas mixture and type of burner as well as a number of process parameters such as the distance to the substrate and its speed relative to the burner, the precursor flow and the number of burner runs, can be adjusted and controlled.

 

Application

  • Powder coating of glass
  • Digital printing
  • Glass protection
  • Diffusion barrier against alkali ions
  • Avoidance of glass corrosion (flat glass, used glass)
  • Increase of optical transmission
  • Anti-reflection-coatings
  • Reduction of light reflection
  • Reduction of soiling
  • Photovoltaics
  • Displays (glass, transparent polymers)
