Abstract

Calcination is a simple method to produce silica from rice husk (RH). One of the key to obtain higher purity silica from rice husk by calcination method is the effectiveness of impurities removal, especially potassium, from RH surface before calcination process. So, in the present study, an attempt has been made to produce high purity silica powder by using calcination method with the combination of roasting-quenching and acid leaching as a pretreatment to eliminate metal impurities, especially potassium, detected by using inductively coupled plasma mass spectrometry (ICP-MS). Finally, the high purity silica, 99.928% was obtained by roasting and calcination temperature of 300°C and 650°C, respectively. However, by considering less energy usage and silica purity achievement, the combination of 300°C roasting-quenching, 1M hydrochloric acid leaching, and calcination at the temperature of 600°C was the best route.
