   Sammanfattning : Several zeolite phases, zeolite N-Y, N-A, ZSM-2, (hydroxy)sodalite and TPA-silicalite- 1, have been synthesized in the form of stable suspensions of discrete colloidal crystals wherein the average particle size is less than 150 nanometers and in certain cases, less than 50 nanometers, with a narrow particle size distribution, PSD. Clear homogeneous tetraalkylammonium (alumino)silicate solutions containing controlled amounts of alkali metal cations are hydrothermally treated at 100 °C without stirring and under reflux. LÄS MER
