ABSTRACT:
Transparent glass sheets comprising thereon titanium-nitride as the principal solar screening layer for reducing transmission of near infrared and, thereover, a layer of tin oxide of about 300 to 800 angstroms thick. The tin oxide layer serves to protect the titanium nitride from oxidation during high-temperature processing procedures, increases the abrasion-resistance, and at roughly the midpoint of the 300 to 800 angstrom range, is useful in reducing the color and visible reflectivity properties of some titanium nitride films. In practice, some of the tin oxide, that is not required for physical protection of the TiN or visual effect, can be positioned between the nitride and the glass substrate.
