Wettability of Carbon (C), Silicon Carbide (SiC), and Silicon Nitride (Si3N4) with Liquid Silicon (Si)

Separation of the solid inclusions formed during the refining process is one of the major challenges associated with metallurgical refining of silicon (Si). Wettability of solid carbon (C), silicon carbide (SiC) and silicon nitride (Si3N4) substrates with liquid silicon was examined using sessile drop technique. This study was performed with the aim of finding the appropriate temperature for separating the above inclusions from liquid Si. …
