This invention relates to the field of high-purity aluminum and aluminum alloy production technology, and particularly to a porous alumina ceramic material, its preparation method, and its application. The material comprises a composite aggregate and an organic binder, wherein the mass ratio of the composite aggregate to the organic binder is 47:3. The composite aggregate comprises 9 wt%–17 wt% inorganic binder and 83 wt%–91 wt% aggregate particles. The inorganic binder comprises: 40 wt%–50 wt% B₂O₃, 20 wt%–29 wt% Al₂O₃, 10 wt%–15 wt% SiO₂, 9.4 wt%–14.4 wt% MgO, 0–0.5 wt% Na₂O, 0–0.5 wt% K₂O, and 0–10 wt% Re₂O₃, where Re is a rare earth element. This method uses corundum or α-Al₂O₃ as a framework and rare earth composite oxides as an inorganic binder. A high-temperature reaction forms sintering necks between the aggregate particles, resulting in a porous alumina ceramic with a bimodal pore distribution.
