喷雾热分解法制备氧化锆纤维的过程研究

Synthesis of Zirconia Fibers by Spray Pyrolysis

本文研究了喷雾热解法制备氧化锆纤维的过程．用醋酸氧锆为前驱体能够制备出直径1～2μm、长度1～5cm的氧化锆纤维．研究了前驱体溶液浓度、表面张力、粘度对产品形貌的影响．通过控制操作条件，可以得到实心或空心纤维．

Zirconia fibers, 1~2μm in diameter and 1~5cm in length, were synthesized by spray pyrolysisof airconyl acetate solutions. The effects of precursor solution concentration, surface tension,viscosity on morphology of the resultant fibers were studied. Solid and hollow fibers were obtainedby controlling the operating parameters.
