· JVASP-10546· K2SnSe3

K2SnSe3 is a ternary ceramic compound combining potassium, tin, and selenium in a fixed stoichiometric ratio, belonging to the family of metal chalcogenide ceramics. This material is primarily of research and development interest rather than established in high-volume industrial production, with potential applications in semiconductor devices, photovoltaic systems, and thermal management where its layered crystal structure and moderate elastic properties could offer advantages in specialized optoelectronic or thermoelectric applications.
