摘要

Highlights?Capillaries can effectively reduce impact of convection on diffusion direction.?Diffusion coefficient of B2O3in 0.37CaO-0.63SiO2slag at 1723?K is 5.24?×?10?9?m2·s?1.?Mass transfer coefficient of B2O3in 0.37CaO-0.63SiO2slag at 1723?K is 6.2?×?10?6?m·s?1.?Mass transfer of B2O3in calcium silicate slag is rate-controlling step for B removal.AbstractMass transfer of boron within silicon and slag is a critical component in boron removal from metallurgical grade silicon by slag refining. To clarify the mechanism of B mass transfer in slag, the prese
