ceramic

· JVASP-45132· Na3CoSiCO7

Na3CoSiCO7 is a mixed-metal oxide ceramic compound containing sodium, cobalt, silicon, and carbonate phases. This is a research-stage material rather than an established commercial ceramic; compounds in this family are studied for potential applications in battery materials, catalysis, and solid-state ion conductors where the combination of alkali metal, transition metal, and silicate phases offers opportunities for tunable chemical and electrochemical properties.
