<p>Methods are disclosed for obtaining a preferred multi-component metallic oxide coating on the surface of a glass substrate by pyrolytic coating techniques. In a pyrolytic coating technique, a heat decomposable, non-homogeneous, dry powder mixture of organic based metallic salts is sprayed against the surface of the glass substrate while the surface is at a temperature in the range from 700 DEG F (370 DEG C) to 1200 DEG F (650 DEG C). In accordance with the general teachings of this specification, the methods are initiated by selecting a preferred composition for the metallic oxide coating to be developed on the surface of the substrate. Different spraying compositions under a single set of spraying conditions or a single spray composition under different sets of spraying conditions are applied to test substrates to develop test specimens. The chemical composition of the coating developed on the test specimens is determined and the spraying composition or spraying conditions which produced the preferred composition is then selected for use in spraying commercial quantities of a glass substrate.</p> |
