PROBLEM TO BE SOLVED: To provide a production method of reclaimed silicon carbide powder having few impurities that uses a silicon carbide residual remaining after practicing a sublimation recrystallization method.SOLUTION: A production method of reclaimed silicon carbide powder reuses a silicon carbide residual remaining after sublimating silicon carbide powder 5 housed in a carbon crucible 1 by a sublimation recrystallization method as a sublimation object of the sublimation recrystallization method. The production method of reclaimed silicon carbide powder includes a separation step for separating a block object containing the silicon carbide residual from the carbon crucible 1 housing the silicon carbide residual, a crushing step for crushing the block object separated in the separation step to obtain a ground product, and a heating step for heating the ground product obtained in the crushing step to obtain reclaimed silicon carbide powder.SELECTED DRAWING: Figure 1 |
