Used as a flux in ceramic and glass manufacturing to improve hardness, thermal stability, and resistance to corrosion. Plays a role in lithium-ion battery technology, particularly in the development of solid-state electrolytes due to its lithium ion conductivity. Employed in air purification systems, especially in confined environments like spacecraft, where it absorbs carbon dioxide from the air. Also utilized in the production of certain types of lubricating greases and as a component in some welding processes to stabilize arcs and reduce spatter.
