Recycling and Characterisation of Amorphous Silica from Zr-Containing Silica Residue

Abstract:

Article Preview

Preparation of amorphous silica using Zr-containing silica residue and the properties of the product have been studied. The results show that the separation of amorphous silica from Zr component can be realized using a process flow that pulping, grinding, washing and solid-liquid separation. The main constituent of the product is amorphous state, the content of SiO2 in the product comes up to 94.3%, the content of ZrO2 comes up to 7.48%, the grain size is 2-3 μm, the surface area is 494.3 m2/g. The quality of the recovery can meet the requirement of white carbon black standards ISO 5794-1 and HG/T 3061.
