Ba4 Y2 B4 Cl2 O12

Ba₄Y₂B₄Cl₂O₁₂ is an oxychloride ceramic compound combining barium, yttrium, boron, chlorine, and oxygen in a mixed-anion crystal structure. This is a research-phase material explored primarily in solid-state chemistry and materials science contexts for its potential as an ionic conductor or luminescent host; it belongs to the family of complex oxide ceramics with mixed-valence metal centers and halide incorporation. The inclusion of rare-earth yttrium and barium in a borate-chloride framework makes this composition relevant to emerging applications in solid electrolytes, photonic materials, or specialized refractory systems, though industrial deployment remains limited and material behavior is not yet standardized for engineering practice.
