    Zirconium dioxide. Zirconium dioxide (zirconia) has a polar surface with zirconium atoms as strong Lewis acid sites. Because of empty orbitals, Zr attracts electron-rich Lewis bases such as phosphate anions. Hence, the surface of zirconia has significant cation-exchange properties, giving rise to a mixed-mode retention mechanism.
