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. This paper discusses the diffusivity of B in the slag from secondary data collated from previous kinetics studies and compares it with semi-empirical diffusivity equations. Graphical Abstract
