W0.95O2.95Co0.1O0.15

This is a tungsten oxide-based ceramic composite doped with cobalt and oxygen, representing a mixed-valence transition metal oxide system. Materials in this class are primarily investigated for energy storage, catalysis, and electronic applications where the cobalt dopant modifies the electronic structure and oxygen stoichiometry of the tungsten oxide host. The cobalt incorporation and controlled oxygen content make this compound of interest for electrochemical devices and catalytic systems where tuning oxidation states and defect chemistry is critical, though this specific composition appears to be a research material rather than an established industrial compound.
