摘要
在硝酸铝溶液中加入乳酸,制备乳酸铝溶胶;在乳酸铝溶胶中加入正硅酸乙酯(TEOS),用溶胶-凝胶法制备了莫来石纤维。在制备莫来石前躯体溶胶时,加入氢氧化钠,研究了钠对莫来石纤维形貌的影响。发现凝胶纤维在1300℃煅烧4h后,纤维表面有片状的氧化铝生成。
The aluminum lactic sol was prepared by mixing aluminum nitrate solution and lactic acid, followed by adding tetraethylorthosilicate (TEOS) in the sol to prepare mullite fibers. The effect of Na on the fiber morphology was studied by adding NaOH in precursor. The results indicated plate-like alumina was observed on fiber surface by sintering at 1300℃ for 4h.
