The number of steps can be reduced in one step without the need for machining such as. Also,
By combining carbon powder and resin binder,
Pitch and tar are added to conventional petroleum-based or coal-based coke as a binder, and once shaped into a certain shape by press molding, etc., baked, and pitch or resin impregnation and baking are repeated to graphitize and cook this.
