Application
Lithium oxide, typically found as a finely divided white powder or crusty material, serves multiple purposes across various industries due to its reactive nature. It readily absorbs carbon dioxide and water from the atmosphere and is produced by heating lithium hydroxide to approximately 800°C in a vacuum or through the thermal decomposition of lithium peroxide. Primarily, lithium oxide finds applications in ceramics and special glass formulations, acting as a flux in ceramic glazes and co-dopant with yttria in zirconia ceramic top coats. Its role extends to power electronics, where it serves as the cathode in lithium-ion batteries used in mobile phones, laptops, and electric vehicles. Lithium oxide is integral in producing lithium hydroxide and lithium metal via electrolysis, highlights its versatility. Its solubility in water results in the formation of lithium hydroxide, a strong base that typically reacts with acidic gases and liquids to produce lithium salts. Moreover, at elevated temperatures, lithium oxide engages in high-temperature reactions with a wide range of solid nonmetal oxides such as SiO2 and B2O3, as well as metal oxides like Al2O3 and Fe2O3, underpinning its utility as a fluxing agent. However, caution is necessary to prevent reactive interactions with containers when used at high temperatures.
