Heat treatable, durable IR-reflecting sputter-coated glasses and method of making same

A heat treatment used in automotive and construction glass, durability and chemical resistance of the coating system, it consists of a layer of nickel or nickel alloys of metal layers, their outsourcing level four on three silicon nitride (Si3N4). Coating system can include a layer of four three silicon nitride (Si3N4) inner liner, metal layers may also include four three silicon nitride. Metal layer that partially surrounded by oxidation or chemical measurement of metal oxides. However, the metal layer should not contain nitrogen compounds.
