· JVASP-57523· Tl2CuAsO4

Tl2CuAsO4 is an inorganic ceramic compound containing thallium, copper, and arsenic oxyanions, belonging to the family of mixed-metal arsenate ceramics. This is primarily a research material studied for its crystal structure and potential electronic properties rather than an established engineering ceramic in widespread industrial use. The material represents a niche area of materials science focused on exploring novel combinations of heavy metals and oxyanions for specialized applications in solid-state chemistry and materials physics.
