Effect of Fluxing Agent B2O3 on Melting Temperature of CaO-Based Refining Slag
Effects of B2O3 on melting temperature of two CaO-based refining slag series with low basicity [ ( CaO)/ (SiO2)=3 ~4] and high basicity [ (CaO)/(SiO2)= 5 〜7. 5 ] have been studied. Results indicate that B2O3is more available than Al2O3and CaF2to decrease

On The Diffusivity of Boron in Slag During Silicon Refining
AbstractSlag treatment is one of the pyrometallurgical routes to refine and remove impurities (such as boron) from silicon. Many studies have demonstrated that the rate-controlling step in the process is the mass transfer of boron (B) in the slag phase. Hence, information regarding the B diffusivity is vital.
