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