· O14 Ca4 Ta4

O14Ca4Ta4 is an experimental oxide compound combining calcium and tantalum in a specific stoichiometric ratio, belonging to the complex metal oxide family of semiconductors. This material is primarily of research interest for understanding mixed-metal oxide physics and potential functional ceramic applications, rather than established industrial production. The tantalum-calcium oxide system is investigated for potential use in electronic, photocatalytic, or high-temperature applications where the combination of tantalum's refractory properties and calcium's modifier role in oxide structures may offer advantages over simpler binary or ternary oxides.
