A rare earth stabilized aluminum deficient zeolite having the structure of faujasite is provided. The zeolite is produced by contacting a Y-type zeolite with a dealuminating agent to remove aluminum from the crystal structure of the zeolite and ion exchanging the zeolite with a specified amount of rare earth metal cations to stabilize the aluminum deficient zeolite.

What is stabilized zirconia?

Stabilized Zirconia is widely used in ceramics industry. Pure zirconium oxide undergoes a phase transformation from monoclinic to tetragonal and then to cubic when temperature changes: monoclinic (1173 °C) ——> tetragonal (2370 °C) ——> cubic (2690 °C) ——> melt. The volume will change during the phase transformation.
