Abstract: A rapid preparation method of transition metal borides includes steps of: using a tungsten rod as the cathode, and a block mixture of boron powder and metal oxide as the anode, the block mixture and the tungsten rod are placed in an plasma device; the plasma device is evacuated, and then filled with a buffer gas and an electric arc is started to obtain a transition metal boride. The present disclosure adopts the direct current arc plasma method with the advantages of simple operation, low cost, environmental friendliness and controllable reaction atmosphere to prepare the transition metal boride, the preparation process is simple, the preparation process is fast, and the environment will not be affected.
