Abstract

The wettability of carbon materials by molten silicon was investigated at 1430° under vacuum by using the dispensed drop variant of the sessile drop technique. The results are compared with data in the literature and used to contribute to a comprehensive understanding of wetting in the liquid-Si/solid-C system. Consequences on the dynamics of Liquid Silicon Infiltration (LSI) processes are discussed.
