· ThNpO3

ThNpO3 is a mixed actinide oxide ceramic compound containing thorium and neptunium in a perovskite-like crystal structure. This is a research-phase material studied primarily in nuclear materials science and fundamental actinide chemistry, rather than a commercial engineering material. Interest in this compound focuses on understanding actinide behavior, oxygen stoichiometry effects, and potential applications in advanced nuclear fuel systems or actinide immobilization strategies.
