ceramic

· JVASP-63064· Sr3TaAs3O

Sr3TaAs3O is a complex oxide ceramic compound containing strontium, tantalum, arsenic, and oxygen. This is a research-phase material studied primarily in solid-state chemistry and materials science, rather than an established commercial ceramic. The compound belongs to the family of mixed-metal oxides and arsenides, which are of interest for their potential electronic, photonic, or catalytic properties, though Sr3TaAs3O itself has limited documented industrial applications and remains largely confined to academic investigation.
