A high purity silicon dioxide (97.08%) was obtained by atmosphere thermal decomposition of the acetic acid leached rice husk at 800°C for 15 minutes. Leaching process parameters such as pH of the acid solution, leaching temperature and time were varied. Analysis of all the acid leached thermal decom...
