    Abstract: A process for the manufacture of yttrium-silicon master alloys. Using silicon carbide as a reductant, both yttria and silicon carbide are mixed, placed in a crucible and heated for a period of time in a vacuum furnace whereby the mixture is sintered, yielding the desired product and CO and CO2 gases. The charge is maintained under a dynamic vacuum during heating, holding, and cooling with continuous removal of gaseous reaction products.
