Abstract Rice Husk Ash is a major voluminous and bulky by-product of rice-milling industries
and its disposal is a major environmental concern. Considering this, a green technology was …

Rice husk is a form of agricultural biomass that provides an abundant silicon source. Rice
husks are widely burnt in agricultural fields in India because it is difficult to find other uses for …

Rice husk is a form of agricultural biomass that provides an abundant silicon source. This
study used rice husk as a raw material to prepare nanosilica without adding an extra …

Silica is a major inorganic component of rice husk and present in the form of nanoparticle in
it. Therefore, it is possible to extract high purity amorphous silica nanoparticles by simple …

The major interest of the paper deals with the extraction of silica from four natural sources
such as rice husk, bamboo leaves, sugarcane bagasse and groundnut shell. These waste …

The objective of the present work is to develop a green procedure for preparation of silica
powders from rice husk ash (RHA) via a carbonation route. The raw materials, RHA and …

A chemical method to synthesize amorphous silica nanoparticles from the incinerated paddy
straw has been introduced. The synthesis was conducted through the hydrolysis by alkaline …

An extract of nanosilica from rice husk, an agriculture waste is used to produce nanosilica
when rice husk ash is burnt in a muffle furnace at 650 C for 4 hrs amorphous silica is …

This work presented a laboratory studies on the preparation of rice husk ash by burning at
700 oC for 3 and 6 h, respectively. Consequently, silica content obtained after heat treatment …

Rice husk (RH), an inexpensive waste material, was used to produce nanosilica. Acid
treatment of RH followed by thermal combustion under controlled conditions gave 22.50 …
