COATING OF GLASS

摘要

The invention relates to the coating of flat glass with indium oxide. Indium oxide coatings, optionally doped, for example with tin, are produced in high yield by utilising a chemical vapour deposition process in which a gaseous mixture of an indium precursor compound and a source of oxygen is directed on to the hot glass surface; the indium precursor compound is preferably a dialkylindium compound (which may also be used without pre-mixing but with separate supply of the oxygen source to the glass surface). The processes of the invention are especially suitable for application of a doped indium oxide coating to a continuous ribbon of glass on the production line on which the glass is formed, for use, for example, in architectural glazing applications utilizing the low emissivity of the coating.
