Abstract:
1. A method of fixing a seed crystal to be used for growing a silicon carbide single crystal from the seed crystal that has been fixed to a graphite base, the method comprising: forming a layered product by placing a metallic material whose melting point is less than a growth temperature of the single crystal on the graphite base, disposing the seed crystal on the metallic material, and then further placing a pressing member for imposing a load on the seed crystal thereon; heat-treating the layered product at a temperature to fix the graphite base, the metallic material, and the seed crystal to each other to form one body, the temperature being not lower than the melting point of the metallic material but not higher than the growth temperature of the single crystal; cooling the layered product; and then removing the pressing member from the layered product, wherein the metallic material is at least one material selected from the group consisting of titanium, vanadium, and zirconium.
