Synthesis of aluminosilicate from impregnation of rice husk

This study was carried out to produce aluminosilicate from impregnation method. In this study rice husk was impregnated into with aluminum nitrate solution. Rice husk act as silica source, while aluminum nitrate contribute to alumina source in synthesizing aluminosilicateT. he rice husk was impregnatedw ith different concentrationo f aluminum nitrate. From the result obtained at temperature 200°C till 600°C in 2 mol concentration of aluminum nitrate, there were no peaks formed. This is because crystallization of mineral does not occur at low temperature. So, at temperature of 800° C there have several peaks occur at 20 anige of 35.00°to 40.00°, 45.00°to 50.00 to 65.00°to 70.00° that can be observe but the peak Intensity was too low for XRD to analyzed it. Andalusite do not formed at this temperature and concentration. For AS2 sample, at 200°C till 600°C there have only one observable peak occur at 20 angle around 45.00° , the mineral present cannot be identified. At this temperature and concentration andalusite still does not formed. Andalusite and alumina was formed at AS2 800t sample. Its occur at 20 angle of 19.280"", 23.172° and 25.165 ° For XRD pattern of alumina its occur at 20 angle of 16.441,20.058 and 21.7050
