“…Ouaddah et al [24]proposed a model for the presence of silicon carbide precipitates at the solid-liquid interface during silicon-based solidification processes . Bornside et al explored the formation mechanism of silicon-carbon impurities in the system by simulating the convection and diffusion of SiO and CO in the furnace during the production of monocrystalline silicon by the straight drawing process(CZ).…”

Carbon etching and silicide deposition are common phenomena in furnaces during photovoltaic crystal pulling processes,both of which decrease Graphite components in the furnace service life and pollute silicon-based materials. SiC as one of the major silicides and carbon etching products whose generation mechanism is of practical significance. Therefore, this study took discarded graphite infusion cylinders with significantly different apparent morphologies as the research objects. Through systematic characterization and thermodynamic analysis, we investigated the physical and chemical reactions that occurred during the generation of SiC in various regions of a discarded graphite infusion cylinder. We derived the SiC delamination, infiltration, and phagocytosis mechanism to explain the formation of the apparent morphological characteristics of the waste graphite infusion cylinder. We also described Generation mechanism of SiC in graphite infusion cylinder during photovoltaic crystal pulling process to provide a theoretical basis for prolonging the service life of the graphite infusion cylinder and treating waste graphite infusion cylinder .
