Abstract

A coated article is provided which may be heat treated (e.g., thermally tempered) in certain example instances. In certain example embodiments, the coated article includes a low-emissivity (low-E) coating having a zinc stannate based layer provided over a silver-based infrared (IR) reflecting layer, where the zinc stannate based layer is preferably located between first and second silver based IR reflecting layers. The zinc stannate based layer may be provided between and contacting (i) an upper contact layer of or including Ni and/or Cr (or Ti, or TiOx), and (ii) a layer of or including silicon nitride.
