In a conventional process, Silica is manufactured by sand fusion of high purity silica sand as the feedstock. This technique is highly energy intensive as it requires the reactants to be heated to temperature as high as 1400°C. Rice Husk rice husk contains silica in range of 80-90 % wt. The silica in rice husk exists in the hydrated amorphous form like silica gel.
