ABSTRACT:
A coated article is provided so as to include a solar control coating having an infrared (IR) reflecting layer sandwiched between at least a pair of dielectric layers. The IR reflecting layer includes niobium nitride (NbxNy). The use of niobium nitride enables the coated article to have good corrosion resistance to acid(s), good mechanical performance such as scratch resistance, and/or good color stability (i.e., a low ΔE* value(s)) upon heat treatment (HT). The coated article may be heat treated (e.g., thermally tempered) in certain example embodiments of the invention.
