· JVASP-63256· K3NdAs2S8

K3NdAs2S8 is a rare-earth chalcogenide ceramic compound containing potassium, neodymium, arsenic, and sulfur elements. This is a research-phase material primarily investigated for its optical and electronic properties within the solid-state chemistry and materials science community, rather than an established industrial ceramic. The neodymium-based chalcogenide family shows promise for infrared photonics, nonlinear optical applications, and semiconducting devices, though K3NdAs2S8 remains at the exploratory stage with limited real-world production or deployment compared to conventional ceramics.
