Abstract

This research investigated the difference of silica from rice husk ash which come from three varieties of rice; Sticky rice (RD 6), Kaowong sticky rice and jasmine rice (RD 105) by non-reflux and reflux techniques. Then heat treatment at 650°C for 1, 3, 5 and 7 hrs. The result showed that that the Sticky rice (RD 6) that heat treatment for 7 hrs. by non-reflux and reflux techniques gave the highest amount of silica 93.249 wt% and 99.086 wt%, respectively. Then the rice hush ash was be analyzed microstructure by SEM, elemental and quantitative analysis by XRF technique and crystal structure by XRD technique.
