Used as a corrosion inhibitor in industrial water treatment systems, helping to protect metal surfaces in cooling towers and heat exchangers. Also employed in pigments for ceramics and glass due to its thermal stability and color properties. Acts as a solid lubricant additive in high-temperature applications where traditional lubricants degrade. Investigated for use in catalytic processes involving oxidation reactions. Shows potential in electrochromic devices and sensors because of its electronic and optical characteristics.
