· JVASP-5665· TaTe2Cl6

TaTe2Cl6 is a layered halide ceramic compound combining tantalum, tellurium, and chlorine elements, belonging to the family of transition metal halide ceramics. This material is primarily of research interest rather than established industrial production, with potential applications in solid-state electronics and optoelectronics where its layered structure could enable tunable electronic properties. The tantalum-tellurium-halide system is being investigated for next-generation semiconductor devices and energy storage materials, where the chemical tunability of halide perovskite analogs offers advantages in customizing bandgap, thermal stability, and ion transport compared to conventional oxide ceramics.
