A Review of Slag Refining of Silicon Alloys
JOM, 2020Slag refining of silicon has been modified in recent years by combining the process with solvent refining, in which an alloy of silicon is first treated by slag and then solidified under controlled conditions to yield high-purity silicon crystals. This paper discusses the effect of alloying elements on the efficiency of slag treatment.

Research Progress of Desulfurization Refining Slag: A Review
steel research international, 2023The development of refining slag is the core of the ladle furnace (LF) refining processes and is essential for fast and effective desulfurization refining. Desulfurization reactions are mainly determined by slag–steel interactions, which are closely related to the physicochemical properties of slags.

A Review of Slag Refining of Crude Silicon
JOM, 2020Metallurgical refining of crude silicon for low-cost, mass production of solar silicon has been studied extensively over the past two decades. One of the methods attempted to target the deleterious impurities of Si is slag refining, where liquid Si or its alloys are treated with a flux.

The Slagging Model Research of Refining-Slag for High Aluminum Steel
Advanced Materials Research, 2012To accurately control the Si content and ensure the function of slag refining in high aluminum steel, the direction and limits of reduction reaction for SiO2 were analyzed based on the thermodynamics. In addition, the thermodynamic prediction model of multi-element slag was studied.

Refining Slag Treatment with Flotation Cell
Advanced Materials Research, 2014In past years, the exploitation of mineral resource in our country was stressed on capacity and the solid waste recycle and innocent treatment was ignored. Much valuable metal is associated and coexist with waste, it is in difficult position for present technology to recycle valuable composition in that waste, which leads to valuable component loss and

A Model for Slag Eyes in Steel Refining Ladles Covered with Thick Slag
Metallurgical and Materials Transactions B, 2014During inert gas stirring in steel ladles, the overlying slag is pushed to the side by the rising gas-metal plume, resulting in an open eye of exposed steel. The present work is devoted to the modeling of ladle eyes in a bath covered with a thick slag layer, where the eyes formed are often smaller than the cross-section of the gas-metal plume.

The Kinetics of Boron Transfer in Slag Refining of Silicon
JOM, 2012Slag refining is one of the few metallurgical methods for efficient removal of boron from silicon. In industrial slag refining for production of silicon for photovoltaic applications, the relationship between the slag composition and the mass transfer rate of boron from metal to slag is of great importance.
