Abstract
A method is provided for preparing piezoelectric fibers by concentrating a solution containing at least two metal alkoxides, a carboxylic acid and lead alkanoate to form a viscous liquid. The viscous liquid is drawn into amorphous fibers and the fibers are calcined and sintered to form the crystalline piezoelectric fibers.
