Correction: Preparation of High Purity Crystalline Silicon by Electro-Catalytic Reduction of Sodium Hexafluorosilicate with Sodium below 180°C.

[This corrects the article DOI: 10.1371/journal.pone.0105537.].

There is an error in the third paragraph of the Introduction and the first equation. The 2 in Na2SiF6 should be subscripted. The correct sentence and the correct first equation are: The well-known Stanford Research Institute International (SRI) reduction process involves that purified silicon tetrafluoride (SiF4) gas through fractional distillation is reduced to silicon by metal sodium above 500°C. SiF4 is from the heat decomposition of sodium hexafluorosilicate (Na2SiF6) at 647°C:

In the Results and Discussion, there is an error in the third equation. The letter “P” was inadvertently added to the second value. Please view the complete, correct equation here:
