Used in the production of ceramics and glass to improve durability and thermal stability. Commonly employed in pyrotechnics to generate red-colored flames due to its ability to emit specific wavelengths when burned. Serves as a component in certain types of drilling fluids in the oil and gas industry, where it helps control wellbore pressure and stabilize formations. Also investigated for use in luminescent materials and phosphors for display technologies. Its low solubility makes it suitable for applications requiring chemical inertness in aqueous environments.
