A method of pyrolytically forming a silicon oxide coating on a hot glass substrate as it travels past a coating chamber comprises contacting the substrate, with silane-containing coating precursor material in the presence of oxygen. The, silane-containing coating precursor material is in the vapour phase and it and gaseous oxygen are intimately mixed before they enter the coating chamber to contact the substrate. Silane as coating precursor material may be conveyed towards the coating chamber in vapour phase in a substantially inert carrier gas, stream and oxygen introduced into the silane-containing earner gas stream before, it enters the coating chamber. The coating operation may take …

Why it's free to use
- Filed June 18, 1990 and granted October 16, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 18, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 18, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
