The invention provides an inert anode material, a preparation method and application, divalent metal hydroxides and trivalent metal hydroxides are used as raw materials, a spinel-based ceramic phase is synthesized in situ by using a cold sintering process, and metal powder is added as a metal phase to obtain the inert anode material containing the ceramic phase and the metal phase. The conductivity of the inert anode material is increased by utilizing the existence of the metal phase, so that the inert anode material is more easily connected with an external circuit. Meanwhile, the traditional sintering temperature is reduced by virtue of a cold sintering process, so that the sintering energy consumption is greatly reduced, and the production cost is reduced. The inert anode material prepared by the preparation process has a wide application prospect in the technical field of electrolytic aluminum.
