Abstract
A process for the production of a low emissivity coating on a glass substrate comprising, in sequence, depositing a reflective metal layer, and reactively sputtering a metal oxide layer over the metal layer in the presence of an oxygen scavenger. The oxygen scavenger is preferably a hydrocarbon, in particular methane. The metal oxide layer may comprise tin oxide, zinc oxide, tungsten oxide and other metal oxides are also likely to be suitable.
