Study of Nanosilica from Agricultural Waste to Commercial Materials

During the many last years ago “Nanotechnology” has played the role in a current life;
because of, their outstanding characterizations which are specific surface area and reactivity of
reaction. This review discussed about the preparation of nanosilica from various waste products
(rice husk, rice husk ash, straw rice ash and sugarcane bagasse ash) by using different methods
including sol-gel, flame spray pyrolysis, hydrothermal, precipitation method, and combustion
assisted by the chemicals. The characterization of nanosilica is determined by various techniques.
In addition, the application of nanosilica is focusing on materials that add economic value, which
include that nanohybrid dental composite and nanocomposite polymer.
