Theoretical study on the reaction mechanism of Si₂Cl₆ and HCl catalyzed by amine catalysts

Abstract

The reaction of Si2Cl6 and HCl to form SiHCl3 and SiCl4 catalyzed with aliphatic and aromatic amines was explored in detail by density functional theory calculations. All stagnation points included...

Chlorination of trichlorosilane/chlorodimethylsilane using metal chlorides: experimental and mechanistic investigations

“…Solar energy is a renewable and clean energy that will play an important role in solving the energy crisis. [1][2][3] Therefore, polysilicon has rapidly developed as a raw material for solar photovoltaic cells. It is important to limit the impurities contained in solar-grade polysilicon to obtain higher photoelectric conversion efficiencies.…”

“…The standard for solar-grade polysilicon requires the carbon atom concentration to be less than 5 × 10 18 atoms per cm 3 . 4 Currently, the main process used in producing polysilicon is the improved Siemens method.…”
