Cerium (IV) oxide powder is a rare earth oxide compound available in ultra-high purity forms. With a bandgap of 3.2 eV, it has unique optical properties, being transparent in the visible range but opaque to UV light. This makes it useful as a component of sunglasses lenses. This powder also has strong oxidation capabilities, allowing it to be used as a catalyst in catalytic converters to reduce automobile emissions. We offer Cerium Oxide Powder in 6 purity grades to meet different needs across research and industry.
