· JVASP-10194· ThSe2

Thorium selenide (ThSe2) is a ceramic compound belonging to the transition metal dichalcogenide family, composed of thorium and selenium in a layered crystal structure. This material is primarily of research and development interest rather than established industrial production, investigated for potential applications in nuclear fuel systems, radiation-resistant coatings, and advanced electronic or photonic devices that exploit the unique electronic properties of layered dichalcogenides. ThSe2 is notable within actinide chemistry as a candidate material where thorium's nuclear characteristics and selenium's semiconducting behavior can be combined for specialized high-performance applications in extreme environments.
