Synthesis of magnesium silicate from wheat husk ash: Effects of parameters on structural and surface properties [PDF]

BioResources, 2012
In the present study, magnesium silicate was produced by using wheat husk ash. Wheat husk was burned at 600 °C to obtain an amorphous ash structure, and the ash was processed with sodium hydroxide solution with heat to extract silica.
