Cobalt Oxide (CAS 1307-96-6) is a stable cobalt(II) oxide, a black to green-brown powder supplied in Technical Grade, and is used as a precursor for lithium cobalt oxide battery cathodes, a deep blue colorant in ceramic glazes and glass, and a catalyst in hydrodesulfurization. It is available in high-purity grades designed for the demanding requirements of the battery and glass sectors.
The compound is valued for its distinctive coloring capabilities, providing deep blue hues in ceramic glazes and artistic glasswork. Its electrochemical properties make it a critical component in the manufacturing of lithium-ion battery cathodes.
As a Technical Grade additive, it enhances the mechanical strength and chemical resistance of specialized enamel coatings. Its high magnetic permeability is leveraged in the creation of magnetic semiconductors and sensors.
