Metallurgical grade silicon (MG-Si) contains iron (Fe) as its main impurity, where
phosphorus (P) is occasionally enriched in the FeSi 2 Ti phase. Based on this phenomenon …

Phosphorus (P) in metallurgical grade silicon (MG-Si) affects the production of downstream
silicon materials. By ignoring the influence of minor elements on P, MG-Si can be …

The global shortage of solar grade silicon for production of solar cells has motivated a lot of
research on the refining of metallurgical grade silicon. However, approaches to upgrade …

Acid leaching of silicon is insufficient in order to achieve solar grade silicon. Leaching of
silicon previously purified by the copper gathering method can significantly reduce amount …

Widespread use of solar energy has not been realized to date because its cost is not
competitive with conventional energy sources. The high price of solar grade silicon has …

The aim of the project is to investigate new material as a reductant in nickel extraction and
purification processes. The analyzed reductants were coke, pig iron, ferrosilicon and two …

One of the major factors in reducing a cost of commercial solar cells is the lifetime of the
photovoltaic material. In this work, a deterioration of Si generated by solvent metal gathering …

An improved method for the modeling of the impurity reduction factor during high-
temperature low-pressure silicon treatment is suggested. The implementation of a modified …
