ceramic

· JVASP-35262· Na2Zn3Se4

Na2Zn3Se4 is a ternary ceramic compound belonging to the chalcogenide family, combining sodium, zinc, and selenium in a crystalline structure. This material is primarily of research interest for optoelectronic and photovoltaic applications, where chalcogenides are explored for their tunable bandgaps and semiconductor properties. While not yet widely deployed in mainstream engineering, compounds in this family show promise for next-generation solar cells, infrared detectors, and solid-state device applications where alternatives like CdTe or CIGS suffer from toxicity or cost constraints.
