Cs2SeClF6

Cs₂SeClF₆ is a halide perovskite ceramic compound containing cesium, selenium, chlorine, and fluorine—a member of the inorganic halide family of materials. This is a research-stage compound that has not yet achieved widespread industrial adoption; it is primarily of interest in the solid-state chemistry and materials science community for its potential as an ionic conductor or in optoelectronic device architectures where halide perovskites show promise. Engineers and researchers evaluate such halide ceramics for next-generation applications where their ionic transport properties, thermal stability, or electronic characteristics might outperform conventional oxides or sulfides.
