Production system for a hafnium crystal bar and the method thereof

The present invention discloses a production system for a hafnium crystal bar and the method thereof. The technical program includes a power supply unit with large DC current, an iodizer, a molybdenum insulator provided inside the iodizer, a thermostatic device, a cooling unit, a vacuum unit, an iodine box for iodizing the iodizer, an electrode unit electrically connected to the power supply unit, wherein the electrode unit is disposed above the iodizer, a crystallization unit provided inside the iodizer, wherein the crystallization unit is connected to the electrode unit, and a rough hafnium provided between the iodizer and the molybdenum insulator. The thermostatic device is a structure with an insulation layer provided outside an inner tank, and an electric heating wire is provided between the inner tank and the insulation layer. The inner tank of the thermostatic device is filled with a saline solution.
