|A manufacturing apparatus of carbide according to the present disclosure includes a tank, a lid, a molten salt crucible, an electrode assembly, an air intake device and a heating device. The lid is connected to the tank to jointly delimit a compartment. The molten salt crucible is disposed in the compartment and configured to hold a salt. The electrode assembly includes a working electrode and a counter electrode. An end of the working electrode and an end of the counter electrode are both in contact with the salt in the molten salt crucible, and the end of the working electrode in contact with the salt is fixed with a reactant tablet. The air intake device is configured to exchange the air in the compartment. The heating device is configured to heat the compartment. The manufacturing apparatus of the present disclosure is adapted for performing the electrochemical reaction between the reactant tablet with amorphous carbon and the molten salt, so as to form the carbide. In this regard, the complexity of the manufacturing process is decreased, and energy consumption and manufacturing cost are significantly reduced.
