The solution growth behavior of silicon carbide (Sic) by a temperature difference method using Fe-Si solvent below 1773K was investigated to clarify the dominant factor affecting growth kinetics. Solution growth experiments were conducted both under the suppression of buoyancy convection and under forced convection controlled by rotating the seed and supply source substrates. In addition, the fluid flow in the solution was estimated by numerical analysis. When buoyancy convection was suppressed, a ridge of SiC grew on the seed substrate only around the edge of the contact area with the solution. Which was affected by Marangoni flow generated by the large temperature gradient. Under forced convection in the solution by substrates rotation, lateral growth of SiC was observed over the entire region of the solution by substrates rotation, lateral growth of Sic was observed over the entire region of the contacting area. Growth rates SiC of 60-160 m/h were obtained for various temperature conditions and were increased proportionally by increasing the supersaturation of carbon at the growth interface. It was thus clarified that the mass transfer of carbon in the solution was the rate-determining step of the solution growth process of SiC. (C) 2013 Elsevier B.V. All rights reserved.
