ResumoLarge crystals of zeolite X with diameters up to 340 μm have been synthesized from gels with the composition 4.76Na2O : 1.0Al2O3 : 3.5SiO2 : 454H2O : 5–8.5TEA. The syntheses were conducted using aqueous slurries of Cab-O-Sil M-5 or Aerosil 200 fumed silica, and sodium aluminate solutions containing triethanolamine made with sodium hydroxide and aluminum wire or sodium aluminate powder.
