ABSTRACT:
This invention relates to alpha (Si, Al)O.sub.4 crystalline complex, and to silica-alumina gel and crystalline alumino silicate host containing said alpha (Si, Al)O.sub.4 complex; both gels and crystalline alumina silicates containing a novel crystalline phase resulting from the hydrothermal treatment of the host (Si, Al)O.sub.4 complexes, both amorphous gel and crystalline alumino silicates, in the presence of rare earth cations.
