Boron removal from metallurgical grade silicon and Si-Sn alloy through slag refining with gas blowing

A combined method of slag refining and gas blowing technique were used for boron removal from metallurgical grade silicon and 75%wt Si-Sn alloy using the 45%CaO-45%SiO₂-10%CaCl₂ slag with the use of Ar gas and Ar-20%O₂ mixed gas. Increasing gas flow rate from 50 to 250 ml/min shows enhancement in B...
