The Pyrosil technique is a well-known process which is used to produce SiOx layers in order to modify surfaces & their properties. This is accomplished by using combustion-chemical vapour deposition (C-CVD) - a cost-saving atmospheric pressure technique. As precursors, both liquid & gaseous compounds can be used. The precursors are pyrolysed by a flame which also serves as a heating source for the substrate allowing both in-line & off-line integration into an existing process. The SiOx coatings have the potential for several different applications, eg, improved long time stability & mechanical stability of hydrophobic coatings on glass, improved adhesion of organic coatings, antireflection & therefore transmission improving properties & so on. Current results & several different aspects for the application of this technology are presented.
