relation to the treatment of rice husk. Rice husk is one of the most silica rich raw materials containing about 9098% silica. Rice husk large ash content and sodium silicate content in the ash it becomes economical to extract silica from the rice husk ash, which has wide market and also takes care of ash disposal. Rice husk is a popular
Sources of rice husk ash (RHA) will be in the rice growing regions of the world, as for example China, India, and the farEast countries. RHA is the product of incineration of rice husk. Most of the evaporable components of rice husk are slowly lost during burning and the primary residues are the silicates.

Hence, rice husk is a natural and renewable biomass source for extraction of silica and subsequently for manufacturing valueadded, siliconbased materials. Currently, most rice husk is combusted directly to produce power or electricity resulting in the production of a large quantity of rice husk ash.
Rice husk pellets as a biomass fuel will ease the environment pressures caused by fossil fuel combustion. Comparing with the burning of rice husk, the burning of rice husk pellets is much more clean. The ash content is around 15 to 16 % when burning directly which will be largely decreased to 6 to 7 % when it is burned in pellet form. 2) Convenient
Rice husk is widely used as the wide distribution and high burning value. It is easy to burn, with less pollution and ash content. Burning rice husk can highly reduce the SO 2 rate of the exhaust compared to use coal. Mainly the rice husk has several ways to use with its burning effect: 1. Used in daily life as fuel for boiling water and ...
burning the rice husk yields 20%25% ash with more than 90% silica. About 35 million ton of paddy is produced in India, which yields more than 7 million ton of rice husk annually.
