Solar energy has received considerable attention over the past few decades, due to its
importance as a green and renewable energy. Low-cost solar-grade silicon production is …

The green, efficient, and pollution-free recycling of metallurgical waste slag has garnered
global attention. This study reviews the latest technologies for the recycling of steel slag (SS) …

Recycling iron and steel is critical for environmental sustainability and essential to close
material loops in circular economics. A major challenge is to produce high-value products …

With the shortage of high-grade silicon (Si) feedstock due to the rapid development of
photovoltaic, electronic information, and organic Si industries, there is an increasing …

Stubborn nonmetallic impurity boron is the most difficult to be removed by the metallurgical
route for solar grade silicon (SoG-Si) production. To break through the restriction of …

Different types of slags have been used to refine silicon, particularly for removing boron
impurity from metallurgical grade (MG) silicon. Although a number of slags have been used …

Equilibrium distribution and transport kinetics of boron between ferrosilicon and calcium
silicate slag were investigated through experimental study. A 50 pct CaO-50 pct SiO 2 slag …

S transfer between molten steel and molten slag was investigated in view of the
electrochemical character of S transfer. C-saturated molten steel containing S was allowed …

Slag structure plays an important role in determining the relative ease of boron removal from
silicon. Correlation between slag structure and boron removal thermodynamics was …

It has been known that desulfurization of a molten steel using a molten slag can be
enhanced by applying an electric field across the slag. In order to evaluate feasibility of the …
