Keywords:太陽電池用シリコン、熱炭素還元

The PV cells based-silicon market grows in a rapid way, which required improvement of the actual production methods of solar grade silicon (SoG-Si).
At the reaction of silica and carbon, the reaction in an interface is important.
We will discuss the interface reaction, investigating weight change and CO gas discharge in real time.
