It is one of the agricultural byproducts from rice milling industries. Rice husk ash consists of more than 90% amorphous silica (Li et al. Citation 2011). To produce Nanosilicon crystalline particles from rice husk ash a magnesiothermic reduction method which involves the activation of the ash with an alkali, sodium hydroxide solution is applied.
