High‐pressure ion exchange of small‐pore zeolite K‐natrolite allows immobilization of nominally non‐exchangeable aliovalent cations such as trivalent europium. A sample exchanged at 3.0(1) GPa and 250 °C contains about 4.7 Eu III ions per unit cell, which is equivalent to over 90 % of the K + cations being exchanged (see picture).
