Study of Pellets and Lumps as Raw Materials in Silicon

May 20 2011 · Laboratory-scale carbothermic reduction experiments have been carried out in an induction furnace. High-purity silicon carbide and two different high-purity hydrothermal quartzes were charged as raw materials at different molar ratios.

GROWTH OF SILICON CARBIDE FROM SOLUTIONScienceDirect

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.
