Abstract
Lead titanate ceramic fibers are excellent piezoelectric and pyroelectric materials,In order to synthesize the ceramic fibers with high-performance,the preparation of the stable sol is very imporant step.The effects of different solvents of the tetrabutyl titanate-lead acetate trihydrate-solvent-catalyst systems on the stability of sol,the annealing temperature and the morphology of ceramic fibers have been investigated by the measurement of TGA-DTA、XRD、SEM method.Comprehensive consideration,The most suitable solvent for the optimized systems is selected out.
