Lanthanum oxide is a white, odorless solid that is soluble in dilute acid but insoluble in water.
It is a rare earth oxide compound, which is a basic anhydride and can therefore react with acids and with strong reducing agents in redox reactions. Rare earth oxide compounds contain at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable, which makes them useful in ceramic structures. For this reason, Lanthanum oxide has a wide range of applications from producing clay bowls to advanced electronics. Lanthanum oxide is also useful in lightweight structural components in aerospace and electrochemical applications such as fuel cells due to its ionic conductivity.
