摘要
利用上海御桥垃圾焚烧厂的焚烧飞灰为主要原料,通过添加SiO2、Al2O3、NaOH组分在实验室研制成功了以硅灰石(wollastonite)为主晶相的微晶玻璃.该体系微晶玻璃制备的最佳工艺条件为:熔融温度1500℃、熔融时间1h,核化温度为920℃,核化时间1.5h,晶化温度为1150～1180℃,晶化时间为2h.研究结果表明,硅灰石为主晶相的微晶玻璃对Pb、Cr和Cd重金属具有很强的稳定束缚能力.
By utilizing fly ash from the Shanghai Yuqiao municipal solid waste （MSW） incineration plant as the main raw matefial,wollastonite-based glass-ceramics were successfully synthesized in the laboratory by doping with SiO2 , Al2O3, NaOH as chemical conditioner. The optimum preparation condition for the glass-ceramics is as follows：melting at 1500℃ for 1 hour, nucleating at 920℃ for 90 mins, and crystallization at 1150 - 1180℃ for 120 mins. It is indicated that the wollastonite-based glass-ceramics made from MSW fly ash has a strong fixing capacity for heavy metals such as lead （Pb）, chromium（ Cr）, cadmium（Cd）
