ABSTRACT:
A method is disclosed of forming a pyrolytic tin oxide coating on a face of a hot glass substrate during transport of the glass through a coating station into which a coating precursor solution containing a tin compound is sprayed so that the glass is contacted by material from which the tin oxide coating is formed by pyrolysis. The coating is formed by spraying a solution containing at least two additives. These additives and their amounts, and the thickness to which the coating is formed, are selected so that the coating contains doping atoms and has an emissivity in respect of infra-red radiation having wavelengths greater than 3 micrometers of at most 0.3 and a specific internal haze factor of at most 1.5.
The additives dissolved in the coating precursor solution may be selected from at least two of the following groups A, B and C, wherein group A consists of compounds which will result in the coating containing fluorine, group B consists of compounds which will result in the coating containing at least one of antimony, arsenic, vanadium, cobalt, zinc, cadmium, tungsten, tellurium, indium, molybdenum and manganese, and group C consists of oxidizing agents.
