Abstract Boron (B) and phosphorus (P) are the most problematic impurities to be removed in production of solar-grade silicon by metallurgical process. In this work, distribution B P between CaO-(La 2 O 3 )-SiO slags Si-10 mass pct Sn melt was experimentally studied. coefficient increased from 2.93 binary CaO-SiO slag 3.33 3.65 with 10 La additions, respectively. followed acid-leaching experimen...

In recent years, a lot of research has been done in the field of producing soft magnetic nano composites by means of mechanical alloying. These materials indicate more electrical resistance and permeability in comparison with soft magnetic composites (SMCs). In this research, reduction of silicothermal mixed powder (Nickel-oxide, Silicon and Iron) was carried out by mechanical alloying to form ...
