The invention is a method for stabilizing heavy metals of the fly ash, the bottom ash or the soil. The stabilization agents which belong to silicate materials, was added to fly ash bottom ash or soil by sprinkling or directly subjoining mix and so on. After this reaction, low soluble and stabilize Heavy metal-Silicate compounds which were formed and didn't re-leaching heavy metals easily (especially, Pb) in the nature environment, even leaching results could below the regulated values and fill the reuse regulations
