摘要：

Chromium is an essential element which contributes to our life activity. However, since the hexavalent chromium causes health damage, its content in water is strictly limited below 0.05 mg/L as the aqueous and soil environment standard values in Japan. The development of high-efficient stabilization method of the steelmaking slags containing chromium is urgent in order to utilize the slags to civil engineering works. In present work, the elution behavior of chromium from stainless steelmaking slags was clarified. Then, a principle of prevention of hexavalent chromium formation and chromium immobilization by the hydrate formation was discussed.
