Abstract
Maredan clay from the western part of Maredan Village, Siak Regency, Riau
Province can be used as raw material for zeolite synthesis. This study aims to
determine the characteristics of zeolite synthesized with variations in hydrothermal
time. Zeolite synthesis was carried out using the hydrothermal method with time
variations of 5, 6, 20, 24, 36 and 48 hours. Data from the characterization of
Maredan clay using XRF proved that Maredan clay has an Al2O3 content of
32.513% and SiO2 47.751%. XRD analysis showed that the synthesis of zeolite in
samples with different time variations showed peaks of sodalite type zeolite
appearing around 2θ = 14.16˚, 24, 65˚, 31.99˚ and 43.39˚, in addition to sodalite
appeared zeolite A (LTA) in the area 2θ = 27.11˚, 32.54˚, 34.18˚, 42.85˚ and several
peaks of zeolite Y around 2θ = 18.644˚. The zeolite synthesis product in this study
is an impure type of zeolite because it contains several zeolite phases consisting of
sodalite and zeolite Y. The crystallinity and crystal size of sodalite are 21.21; 27.45;
17.32; 16.92; 21.48; 126.81 % and 56.35; 42.28; 59.43; 25.35; 42.28; 126.82 nm.
The crystallinity and crystal size of zeolite A (LTA) are 7.42; 9.99; 15.18; 11.54;
10.93; 5.70 % and 52.09; 43.59; 107.27; 18.6; 52.28; 52.29 nm.
