The invention belongs to the technical field of ultra-high-temperature ceramic materials, and particularly relates to a preparation method of a high-performance zirconium boride-silicon carbide composite ceramic electrode. The method comprises the following specific steps: material taking: weighing silicon carbide powder and zirconium boride powder with certain weight, pouring the two kinds of powder into a grinding device, continuously crushing the two kinds of powder by using the grinding device, fully stirring the two kinds of powder for 8-10 minutes by using a stirring device after complete crushing until the two kinds of powder are completely mixed, adding an excessive ethanol solution, and continuously performing full stirring for 5-7 minutes; and constant-temperature ball milling: pouring the two mixtures into a grinding device, keeping and controlling the temperature to be 30-40 DEG C, and performing constant-temperature ball milling continuously on the mixtures for 2-4 hours. After the constant-temperature ball milling, the toughness of the produced zirconium boride-silicon carbide composite ceramic ceramic electrode is effectively improved, the electrode is not prone to breakage in the later use process, and therefore the quality of the ceramic electrode is improved.

本发明公开的属于超高温陶瓷材料技术领域，具体为一种高性能硼化锆‑碳化硅复相陶瓷电极制备方法，该高性能硼化锆‑碳化硅复相陶瓷电极制备方法的具体步骤流程图如下：取料：称取一定重量的碳化硅粉末和硼化锆粉末，将两种粉末倒入研磨装置的内部，使用研磨装置对两种粉末进行不断粉碎，当完全粉碎后，使用搅拌装置对其进行充分搅拌8‑10分钟，直至完全混合后，向其中加入过量的乙醇溶液，继续充分搅拌5‑7分钟；恒温球磨：将两种混合物倒入研磨装置的内部，保持温度控制在30‑40摄氏度，对其进行持续恒温球磨2‑4小时，恒温球磨之后，生产的硼化锆‑碳化硅复相陶瓷电极的韧性有效提高，在后期使用的过程中不容易发生断裂，从而提高陶瓷电极质量。
