%X Vitrification process can effectively control the leachability of heavy metals in fly ash generated from municipal solid waste incinerator(MWSI).The use of liquid ceramic(LC)additive as a heavy metal chemical stabilization agent was evaluated for MSWI fly ash. The residuals of chromium,lead and zinc in slag increase by different degree with liquid ceramic additive less than 10%.The volatilization of Cr and Zn occurs after 61 minute with 10% addition of LC, and the binding efficiency of Cr decreases with increasing of melting temperature. The results indicate that the binding efficiency of heavy metals was affected greatly by LC additive and showed significant differences according to type of heavy metal during melting process. The short melting time (no longer than 33min) is useful to obtain high binding efficiency of heavy metals.
