- Abstract
A study was conducted in the Department of Chemical Engineering, University of Engineering and Technology, Lahore, Pakistan during the year 2008. In this study an attempt was made to produce wollastonite from rice husk by extracting amorphous silica present in hydrated form. The rice husk, an agro-waste material was treated with potassium permanganate and then incinerated in tube furnace at 600°C for 10 minutes to produce amorphous silica. The amorphous silica was then treated with calcium oxide in presence of water to form calcium hydro silicate (CSH) gel. CSH gels were dried in oven and heated at 800°C in muffle furnace for 60 minutes. The incinerated samples were ground and passed through 100, 200 and 300 mesh sieves and then analyzed by X-Ray Diffraction (XRD). XRD patterns confirmed the formation of wollastonite.
