Titanium nickel niobium alloy barrier for low-emissivity coatings

A method to form a low emissivity coating, comprising

• providing a transparent substrate;
• forming a metal oxide layer on the transparent substrate;
• forming a first layer on the metal oxide layer,
• wherein the first layer comprises silver, wherein the first layer is operable as an infrared reflective layer;
• forming a second layer on the first layer,
• wherein the second layer is operable as a barrier layer for the first layer,
• wherein the second layer comprises titanium, nickel and niobium,
• wherein the percentage of titanium is between 5 and 15 wt %,
• wherein the percentage of nickel is between 30 and 50 wt %,
• wherein the percentage of niobium is between 40 and 60 wt %.

A low emissivity panel, comprising

• a transparent substrate;
• a metal oxide layer disposed on the transparent substrate;
• a first layer disposed on the metal layer, wherein the first layer comprises silver, wherein the first layer is operable as an infrared reflective layer;
• a second layer disposed on the first layer, wherein the second layer is operable as a barrier layer,
• wherein the second layer comprises titanium, nickel and niobium,
• wherein the percentage of titanium is between 5 and 15 wt %,
• wherein the percentage of nickel is between 30 and 50 wt %,
• wherein the percentage of niobium is between 40 and 60 wt %.
