| 抄録: | The kinetic characteristics of electrochemical reduction of SiO₂ granules in molten CaCl₂ were investigated to develop a new process for producing solar-grade silicon. The reduction rate was evaluated based on the time dependence of the reduction fractions measured from the growth of the reduced Si layer and the weight change of the samples during electrolysis. The samples were prepared by potentiostatic electrolysis of SiO₂ granules in molten CaCl₂ at 1123 K. The results indicated that the reduction was fast at the initial stage of electrolysis, and gradually slowed as the reaction progressed. The apparent current density reached 0.7 A cm⁻² at the initial stage, which was comparable to the commercial Hall-Héroult process for aluminum production. |
