The invention discloses a preparation method of a microcrystalline corundum abrasive material. The method comprises the following steps: adding an appropriate amount of hydrochloric acid solution and water into aluminum oxide monohydrate micro-powder which is used as a raw material to ensure that the raw material becomes a stable water sol; then adding manganese oxide to ensure that the water sol is gelatinized; performing drying solidification and crushing on the generated gel body; and then calcining and sintering to prepare an ultracrystalline corundum abrasive material. The preparation method is suitable for large-scale production, the technological process is easy to control, and the obtained ultracrystalline corundum abrasive material is small in particle size, compact in structure, good in obdurability and stable in grinding performance.
