Low-cost magnesium aluminate spinel powder modification treatment method
The invention discloses a low-cost magnesium aluminate spinel powder modification treatment method. A sintering aid, a dispersing agent and a binder are used, high-purity magnesium aluminate spinel powder (the purity is greater than or equal to 99.9%) is used as a raw material, and the process route comprises the following steps: (1) firstly, sequentially putting the weighed sintering aid and magnesium aluminate spinel powder into an organic container filled with the dispersing agent, and carrying out ball milling for 8-10 hours; (2) putting a certain amount of binder into slurry formed by a sintering aid, magnesium aluminate spinel powder and a dispersing agent, and carrying out ball milling for 12-24 hours; and (3) finally, drying, ball-milling and sieving the ball-milled slurry. The method is simple in technological process, low in production cost, high in raw material utilization rate, good in powder sintering activity and easy to prepare in batches. By selecting a proper dispersing agent, the rheological property of the high-purity powder can be effectively improved, biscuit forming is easy, and biscuit compactness can be improved; by adding a proper amount of binder, the size of the modified powder can be controlled.
本发明公开了一种低成本镁铝尖晶石粉体改性处理方法。使用烧结助剂、分散剂和粘结剂，以高纯镁铝尖晶石粉体(纯度≥99.9％)为原料，工艺路线：(1)首先将称量好的烧结助剂和镁铝尖晶石粉体依次放入装有分散剂的有机容器中，球磨8‑10h；(2)其次将一定量的粘结剂放入装有烧结助剂、镁铝尖晶石粉体、分散剂形成的浆料中球磨12h‑24h；(3)最后将球磨完毕的浆料进行干燥、球磨、过筛。本发明工艺流程简单、生产成本低、原材料利用率高、粉体烧结活性好及易于批量化制备。通过选择合适的分散剂，可以有效地增加高纯粉体流变性，易于素坯成型，有利于提升素坯致密度；通过添加适量的粘结剂，可以实现对改性粉体尺寸控制。
