· JVASP-12685· CoH2SeO5

CoH₂SeO₅ is an inorganic ceramic compound containing cobalt, hydrogen, selenium, and oxygen—a mixed-metal selenate belonging to the family of transition metal oxyselenates. This is a specialized research compound rather than an established commercial material; such selenate ceramics are primarily investigated for their crystal structure, ion-transport properties, and potential electrochemical applications in laboratory settings.
