Preparation and Characterisation of Amorphous Silica from Alkali Wastewater Produced in Manufacturing Process of ZrOCl₂

Abstract:

The amorphous silica was prepared from the alkali wastewater rich in Na₂O•nSiO₂ produced in manufacturing process of zirconium oxychloride (ZrOCl₂). The composition and microstructure of amorphous silica were studied by X-ray diffraction, X-ray fluorescence and scanning electron microscope, respectively. The results showed that the amorphous silica was mainly composed of uncrystallized substance, and the silica content was 96.4%. Its whiteness was 97.5% and the particle size was between 100nm and 200nm without agglomeration. The specific surface area of the amorphous silica was 531.9 m²/g, and its pore volume and diameter were 0.945 cm³/g and 4.94 nm, respectively.
