Precipitation of metallic chromium during rapid cooling of Cr<sub>2</sub>O<sub>3</sub> slags
The slag systems of CaO-SiO<sub>2</sub>- Cr<sub>2</sub>O<sub>3</sub> and Al<sub>2</sub>O<sub>3</sub>-CaO-MgO-SiO<sub>2</sub>- Cr<sub>2</sub>O<sub>3</sub> were analyzed. These slag systems occur in the pro...
