Abstract
A method for producing an ingot includes loading a raw material comprising a raw material powder having a D50 of 80 μm or more into a reactor (loading step), controlling the internal temperature of the reactor such that adjacent particles of the raw material powder are interconnected to form a necked raw material (necking step), and sublimating components of the raw material from the necked raw material to grow an ingot (ingot growth step).
