· JVASP-20314· Nd4Sb3

Nd₄Sb₃ is an intermetallic ceramic compound containing neodymium and antimony, belonging to the rare-earth pnictide family of materials. This compound is primarily of research and developmental interest rather than established in high-volume industrial production, with investigation focused on its potential as a thermoelectric material for waste heat recovery and solid-state cooling applications. The neodymium-antimony system is notable for exploring rare-earth electronic properties in ceramic form, offering potential advantages in specialized thermal management where conventional semiconductors are limited.
