· Na2Nb4Se4O19

Na2Nb4Se4O19 is an inorganic ceramic semiconductor compound containing sodium, niobium, selenium, and oxygen elements. This material belongs to the family of mixed-metal selenate oxides and is primarily studied in research contexts for photocatalytic and optoelectronic applications. The niobium-based framework combined with selenate anions creates a structure of interest for energy conversion, environmental remediation, and potential photovoltaic or photodetector device development, though it remains largely in the experimental phase rather than established industrial production.
