dc.description.abstract Rice husk (RH) is available in large quantities in many rice producing areas of Pakistan. The use of rice husk as a fuel in heat generating systems adds to environmental pollution. Rice husk contains approximately 20 % silica which exists in hydrated form. This silica can be retrieved as amorphous silica under proper oxidizing conditions. In present study rice husk was treated with various dosages of potassium permanganate before subjecting to thermal treatment. Potassium permanganate acts as oxidizing agent during combustion process. Various ash samples were prepared by varying the potassium permanganate concentrations and the buming temperatures over long periods. Ash produced was characterized by XRD, FTIR and other analytical methods. It has been observed that low dosages of KMn04 favors the formation of amorphous silica along with low carbon contents. en_US
