| 摘 要： | 采用金属铝粉、甲酸和醋酸为原料，以氯化铝为催化剂制备了羧酸铝溶液。在羧酸铝溶液中加入硅溶胶，制备了可纺的前躯体溶胶。凝胶纤维在1400℃煅烧后，主要物相为莫来石，有少量的氧化铝和氧化硅相，得到的纤维直径均匀，但纤维表面有较多的裂纹。

| Abstract: | Aluminum carboxylates solution were synthesised from dissolution aluminum in a mixture of formic acid and glacial acetic acid using aluminum chloride hexahydrate as catalyst. Spinning mullite precursor sols were prepared using the aluminum solution and silica sol. After the gel fibers were sintered at 1 400℃, the main phase were muUite, a little of alumina and silica. The muUite fibers have uniform diameter, with some flaw in fibers surface. |
