Abstract

The recovery of SiO2 and Al2O3 from the alkali waste solution of the glass polishing powder-recycling process was investigated. The effects of seed crystal, stirring speed, and temperature were also studied. Hydroxysodalite was obtained from the waste solution by heating to 80-100 °C. Addition of seed crystal shortened the reaction time and made easy the recovery of hydroxysodalite. The hydroxysodalite deposition process was rate-determined by the chemical reaction step, and increased temperature was also effective in shortening a reaction time.
