The Characteristic of Synthesized Zeolite Rice Husk Particles via Different Routes

Zeolite particles were synthesized through in-situ extraction of silica from rice husk ash without seeding method in the absence of organic template by a static hydrothermal condition at 100oc/24h at varied ageing 8-24h. the effect of amorphous silica content on ageing time of synthesis products was evaluated with x-ray diffraction (xrd), fourier transform infrared (ftir) and field emission microscopy (fesem). the present of zeolite y without seeding method by xrd analysis show a mixture of zeolite a, y and p. the transformation of amorphous rice husk particle gradually increased as early at 8 hours in ageing and increased with increase in ageing reaction. the vibration bands at around 974 cm^-1 indicated si-oh vibrations of the surface silanols, which is the characteristic of mesoporous silica. the fesem images showed cubic-shaped morphology of the powders increased with increase in ageing reaction.
