Abstract: A manufacturing method of a carbide includes steps as follows. A carbon source is provided, a contacting step, a heating step and an electrochemical step are performed. The carbon source includes an amorphous carbon and a compound. The compound is a chalcogen compound, a pnictide compound, a halide, a hydroxide or a salt of a metal or a metalloid. 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 to form a heated reactant. In the electrochemical step, a current is applied to the heated reactant, wherein the current passes through the carbon source, so as to make the alkaline earth metal halide, the amorphous carbon and the compound react with one another to form a carbide of the metal or the metalloid.

Abstract: A manufacturing apparatus of carbide of 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 for containing 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 both contact the salt in the molten salt crucible, and the end of the working electrode contacting the salt is for fixing 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.
