<p>Adding an Al₃Ti refiner is the main way to improve the mechanical properties of aluminum alloys. Sintering is one of the main preparation methods of Al₃Ti; however, the method faces challenges, such as the low recovery of the Al₃Ti phase and difficulty separating the metal from the slag. In this work, we have innovatively proposed a strategy to remove Al₂O₃ during the preparation of Al₃Ti by CaO, and to utilize Al particles to recover Al₃Ti at the same time. The feasibility of adding aluminum particles to recover Al₃Ti has been explored, and the reaction process of separating the Al₃Ti phase by aluminum particles revealed. The results showed that, under the conditions of a sintering temperature of 1500°C, an Al powder ratio of 1.2, and a CaO ratio of 1.6, the recovery rate of Al₃Ti was increased from 55.61% to 89.14% when the aluminum particle ratio was 0.6. With the increase in temperature, the Al₃Ti phase was enriched in the aluminum matrix and the Al₂O₃ phase was enriched in the slag phase, thus realizing desirable metal–slag separation.</p>
