B.G.ArshadSazmal E.AsikJahimin 1220141423Zeolite A was successfully synthesized from natural kaolin procured from KG. Gading, Bongawan Sabah. The raw kaolin was treated with sodium hexametaphosphate to remove the impurities exist in the natural kaolin. The kaolin clay undergoes metakaolinization at 800°C for 5 h transforming it into highly disordered and amorphous. The raw kaolin and metakaolin were characterized under XRF, XRD and SEM. Reaction mixture for zeolite A was obtained by mixing metakaolin and sodium hydroxide without additional silica. The reaction mixture was stirred for 30 min before hydrothermally synthesised at 100°C for 8 h. Optimum condition for the zeolite A synthesis was studied by preparing reaction mixture with varying molarity. The formation of zeolite A and sodalite was strongly influenced by the molarity of the NaOH used in the reaction mixture.]]>Basaldella, E.I., R. Bonetto and J.C.
