Zeolite LZ-277 and process for preparing same.

摘要

A novel aluminosilicate zeolite, denominated LZ-277 is synthesized hydrothermally from aqueous gels in the Na2O - Al2O3 - SiO2 system and in the absence of an organic templating agent. The as-synthesized LZ-277 has a chemical composition on an anhydrous basis expressed in terms of molar oxide ratios of: 1.0 +/- 0.1 Na2O : Al2O3 : 3-15 SiO2 and has a low adsorptive capacity for SF6 compared with the prior known, and possibly topologically related, zeolite Phi.
