Abstract

Rice is the staple food of many countries, especially in the Asia region which holds the highest consumption of rice with 90% globally. Rice husk is a solid agricultural waste of rice milling which needs a proper waste management. Rice Husk are a renewable resource which is widely used to extract nanoparticles for various applications. One such type of nanoparticles which are extracted from rice husk is the silica particles. In order to extract these silica particles various methods and procedures are used. In this review it gives a detailed explanation on how the silica particles are extracted from Rice Husk by various methods of extraction. It also highlights the applications of these extracted nanoparticles and the properties of Rice Husk Ash. Two main methods discussed for the silica extraction are the physical and the chemical method. Additionally, it also highlights the other methods which are used for the process of extraction of silica particles from Rice Husk.
