One Shot of the Hydrothermal Route for the Synthesis of Zeolite LTA Using Kaolin

The zeolite LTA (Z-LTA) was successfully produced from the synthesis of kaolin and well-crystallized using a hydrothermal method. main purpose Z-LTA to illustrate transformation with different molarity alkaline solution crystallization time. heated in furnace for 4 h at 500, 600, 700, 800 °C, resulting metakaolinization process that transformed it into an amorphous state. mixture obtained by dissolving metakaolin sodium hydroxide (NaOH) without adding other silica or alumina sources. Before going through process, aged 24 h. crystal morphology degree crystallinity (%) were evaluated various (M) time (h). increases 62.83 86.8% when NaOH is increased 0.5 1 M but does not increase 2 (80.77% 67.78%), respectively. based on proceeded (h) factors. 9 give highest (88.45%) compared time, 12 (86.16%), 16 (87.11%), (86.80%) 30 (86.59%) structure Na, Al, O, Si seen SEM images NaOH, (Z-LTA, h). particle size h) smaller, 0.329 µm, than kaolin, 0.497 µm. Under low alkali conditions generates high natural kaolin. As result, low-grade Malaysian can be traditional composition parameters are carefully controlled. most cost-effective efficient method, comparable product quality synthesized conventional raw materials.
