Abstract
A new family of crystalline molecular sieves have been synthesized. These compositions have a microporous structure of at least ZrO.sub.3 octahedral units and SiO.sub.2 tetrahedral units. Optionally, the molecular sieves contain M metals such as titanium or tin. These novel molecular sieves are prepared hydrothermally from a reaction mixture composed of reactive sources of the components. Additionally, these molecular sieves are useful for the selective adsorption of ammonium ions.
