The major phase of both slags produced from air and CO/CO2 conditions were SiO2 and Fe2O3, which have much benefit to the encapsulation of heavy metals. The leaching concentration of zinc in CO/CO2 reducing condition is an order less than that in air oxidizing condition due to the higher vapored heavy metals in CO/CO2 reducing condition compared to that in air oxidizing condition. Furthermore, the leaching rate of heavy metals in both CO/CO2 and air conditions are almost the same.

在熔渣特性改变方面，空气气体与CO/CO2还原气氛下所得之熔渣除外观上不同外，两种熔渣之XRD之图谱因熔渣之结晶程度不良，仅可鉴定出SiO2及Fe2O3两种晶相，因而熔渣中之SiO2及Fe2O3可视为较为稳定之晶体结构，故在还原气氛熔融时，对熔渣中重金属之匣限化仍具有正面助益。
