· JVASP-97996· K2WSe4

K2WSe4 is a potassium tungsten selenide compound that belongs to the family of metal chalcogenides—materials combining transition metals with selenium. This is primarily a research and experimental material rather than an established industrial standard, studied for its potential in optoelectronic and thermoelectric applications due to the properties inherent to tungsten-selenium systems. The material is of interest in advanced materials research where transition metal selenides show promise for energy conversion, photovoltaic devices, and solid-state electronics.
