Effect of Fluxing Agent B2O3 on Melting Temperature of CaO-Based Refining Slag

open access: yesTeshugang, 2009
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

open access: yesJournal of Sustainable Metallurgy
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.
