▎ 摘　　要

NOVELTY - Preparing polycrystalline europium titanate-based magnetic refrigeration material comprises (1) uniformly mixing europium trioxide and titanium dioxide and sintering to obtain pre-sintered material, (2) uniformly mixing the reducing agent with the pre-sintered material in the step (1) to obtain mixed material, and (3) reducing and sintering the mixed material in the step (2) to obtain the polycrystalline europium titanate-based magnetic refrigeration material. USE - The method is useful for preparing polycrystalline europium titanate-based magnetic refrigeration derivative materials. ADVANTAGE - The method: has simple operation and high preparation efficiency; and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for polycrystalline europium titanate-based magnetic refrigeration material prepared by the preparation method.
