Bi2SeO2 is an oxy-selenide ceramic compound combining bismuth, selenium, and oxygen—a layered material that belongs to the broader family of bismuth-based ceramics with mixed-valence metal-oxygen frameworks. This is primarily a research-phase compound rather than an established industrial ceramic, investigated for its potential in solid-state electronics, thermal management, and photocatalytic applications due to the electronic properties arising from bismuth's lone pair effects and the layered crystal structure. Engineers would consider this material in exploratory projects targeting alternative thermoelectrics, photocatalytic water treatment systems, or specialized dielectric applications where bismuth-based ceramics offer advantages in cost or environmental profile over conventional oxides.
