Abstract

A method for preparing a SiC ingot includes loading a composition of a raw material comprising a carbon source and a silicon source into a reactor; placing a plurality of seed crystal on one side of the reactor spaced apart from the composition; and sublimating the composition such that the SiC ingot grows from the plurality of seed crystal. A flow factor of the composition may be 5 to 35.
