The Interactions of Carbon and Nitrogen in Liquid Silicon

摘要

The interactions between carbon and nitrogen in liquid silicon have been studied experimentally. High purity silicon was melted in silicon nitride crucibles under an Ar atmosphere with a graphite slab inserted in the crucible prior to melting as a carbon source. The system was thus simultaneously equilibrated with Si_3N_4 and SiC Samples were extracted in the temperature range 1695-1798 K and analyzed using Leco.
