Cobalt-silicon solutions contained in graphite crucibles in the compositional range 0 to 78 percent cobalt have been examined qualitatively as solvents for the growth of large beta silicon carbide crystals at 1600°C. Beta silicon carbide was recovered from quenched alloys with a maximum recovery in the 37 percent cobalt region.
