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, helping control wellbore pressure and stabilize formations. Investigated for use in luminescent materials and phosphors for display technologies. Also explored in medical applications, particularly in radiology, due to its radiopaque properties, making it useful in imaging contrast agents.
