|A manufacturing method of carbide according to the present disclosure includes steps as follows. A carbon source is provided, a contacting step is performed, a heating step is performed and an electrochemical step is performed. The carbon source includes an amorphous carbon and a compound. In the contacting step, the carbon source is disposed in an alkaline earth metal halide to form a reactant. In the heating step, the reactant is heated in an inert atmosphere to form a heated reactant. In the electrochemical step, a current is applied to the heated reactant and passes the carbon source, so that the alkaline earth metal halide, the amorphous carbon and the compound react with one another to form the carbide. The reaction temperature and time of the amorphous carbon and the complexity of manufacturing process are decreased in this manufacturing method, which significantly reduces the energy consumption and manufacturing cost.
