· JVASP-12820· Na3TlO2

Na3TlO2 is an inorganic ceramic compound containing sodium, thallium, and oxygen, representing a mixed-metal oxide in the quaternary oxide family. This is a research-phase material with limited industrial deployment; it belongs to the broader class of heavy-metal oxides being investigated for specialized applications requiring high-density ceramics and potential ionic conductivity. Engineers would consider this compound primarily in experimental contexts where thallium-containing ceramics offer advantages in radiation shielding, scintillation detection, or solid-state electrolyte research, though toxicity concerns and cost typically limit adoption compared to conventional oxide ceramics.
