· JVASP-26419· NdBi2BrO4

NdBi2BrO4 is an ternary oxide ceramic compound containing neodymium, bismuth, bromine, and oxygen—a compositionally complex ceramic in the rare-earth bismuth oxychloride/oxybromide family. This is a research-stage material studied for functional ceramic applications, particularly where high density and moderate elastic stiffness are beneficial; compounds in this family have been investigated for photocatalytic, electronic, and optical properties due to the combination of rare-earth and heavy metal elements. Compared to conventional technical ceramics, rare-earth bismuth oxides offer tunable electronic band structures and potential photocatalytic activity under visible light, making them candidates for advanced functional applications rather than structural load-bearing roles.
