InNbO2S

InNbO2S is an experimental indium niobium oxynitride sulfide ceramic compound that combines transition metal oxides with sulfide chemistry, positioning it at the intersection of conventional oxide ceramics and emerging chalcogenide materials. This material remains primarily in research phase, with potential applications in photocatalysis, optoelectronics, and solid-state ion transport where the mixed-anion framework could enable tunable electronic and ionic properties unavailable in single-anion ceramic systems. Interest in this compound family stems from the ability to engineer bandgaps and defect chemistry through compositional tuning, making it attractive for next-generation functional ceramics where conventional oxides or sulfides alone fall short.
