· JVASP-35119· BaAlSi4N5O3

BaAlSi₄N₅O₃ is an oxynitride ceramic compound combining barium, aluminum, silicon, nitrogen, and oxygen phases. This material belongs to the family of advanced structural ceramics and is primarily investigated in research contexts for high-temperature applications where thermal stability and mechanical performance are critical. The oxynitride composition offers potential advantages in refractory and specialty ceramic applications where conventional oxides or nitrides alone may be insufficient.
