Abstract
Structural ceramic oxide fibers like alpha-Al2O3, MgAl2O4 (spinel), Y3 Al5O12 (YAG) and eutectic Al2O3-Y3Al5O12 as well as the functional Pb( Zr1-xTix)O-3 (PZT) fibers were successfully prepared by sol-gel proces sing. All precursors are based on metal oxohydroxopropionates. A compa rative study of sol-gel routes leading to spinnable sols demonstrates the key role of propionic acid as an excellent agent for controlling h ydrolysis and condensation reactions.
