Abstract

The recycling of ceria-based glass polishing powder by alkali treatment was investigated. Major impurities in the waste, a SiO₂ component from fine glass powder and an Al₂O₃ component from coagulating agents, could be removed easily at 50-60°C in a 4 mol kg^-1 NaOH solution within 1 h. These impurities react with NaOH to precipitate as zeolite at higher temperature. Thus, it is expected that a recycling process which can regenerate polishing powder and convert SiO₂ and Al₂O₃ components into zeolite can be designed.
