Abstract

Slag 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.

论硅精炼过程中熔渣中硼的扩散性

炉渣处理是精炼和去除硅中杂质（如硼）的火法冶金途径之一。许多研究表明，该工艺的速率控制步骤是渣相中硼（B）的质量转移。因此，有关硼扩散性的信息至关重要。本文根据以往动力学研究中整理的二手数据，讨论了硼在炉渣中的扩散性，并将其与半经验扩散方程进行了比较。

期刊介绍： Journal of Sustainable Metallurgy is dedicated to presenting metallurgical processes and related research aimed at improving the sustainability of metal-producing industries, with a particular emphasis on materials recovery, reuse, and recycling. Its editorial scope encompasses new techniques, as well as optimization of existing processes, including utilization, treatment, and management of metallurgically generated residues. Articles on non-technical barriers and drivers that can affect sustainability will also be considered.
