· JVASP-27801· Ta3Br7

Ta3Br7 is a tantalum bromide ceramic compound belonging to the halide ceramic family, characterized by a tantalum-bromine composition that exhibits high density and inherent brittleness typical of ionic ceramic systems. This material remains largely in the research and exploratory phase rather than established industrial production, with potential applications in specialized electronic, optical, or high-temperature environments where halide ceramics offer unique chemical or thermal properties unavailable in conventional oxides or nitrides.
