· NaTlO2

NaTlO2 (sodium thallate) is an inorganic ceramic compound containing thallium oxide in a sodium matrix. While not widely deployed in conventional engineering applications, this material belongs to the family of thallium-based ceramics studied for specialized optical, electronic, and thermal applications due to thallium's high refractive index and density. Its use remains largely confined to research and laboratory settings, where its properties are explored for potential applications in optics, radiation shielding, and advanced ceramic systems, though toxicity concerns and cost limit commercial adoption compared to established ceramic alternatives.
