摘要: 以实验室化学共沉淀法制备的纳米镁铝尖晶石粉体为原料，研究了MgF2、AlF3、TiO2和ZnO四种添加剂对镁铝尖晶石烧结性能的影响。结果表明，TiO2、ZnO能与镁铝尖晶石形成固溶体，可以起到很好促进烧结的作用，而添加MgF2、AlF3的试样开裂、疏松多孔，不利于制品的烧结致密化。
Abstract: The nano magnesium aluminate spinel powders prepared by co-precipitation method in laboratory were used as raw materials. The effects of MgF2, AlF3, TiO2 and ZnO additives on the sinterability of magnesium aluminate spinel were studied. The results show that the solid solution can be formed with magnesium aluminate spinel and TiO2 or ZnO, which can promote the sintering of spinel ceramics. The samples added with MgF2 or AlF3 were cracked and loosely porous, which indicates that they are disadvantageous for the sintering densification of the magnesium aluminate products.
