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

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:

$$N{a}_{2}Si{F}_6(s)=Si{F}_4(g)+2NaF(s)$$ (1)

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:

$$4Na(s)+N{a}_{2}Si{F}_6(s)=Si(s)+6NaF(s)$$ (3)

These errors were introduced during preparation of this manuscript for publication. The publisher apologizes for these errors.
