PREPARATION OF (PB(ZR1-XTIX)O3 FIBERS BY THE ALGINATE METHOD

Continuous Pb(Zr1-xTix)O3 ceramic fibers have been prepared by the alg inate method, which is based on a gelation of sodium alginate aqueous solution by sodium ion-exchange with protons or multivalent metal ions . In this work, a new process by use of a 5% sodium alginate aqueous s olution mixed with ZrO2-sol and TiO2-sol has been studied. The Pb-Zr-T i-alginate precursor fibers were converted to Pb (Zr1-xTix)O3 ceramic fibers by firing at 1200-degrees-C for 3h. The Pb(Zr1-x Tix)O3 ceramic fibers were examined by the powder X-ray diffraction technique and sc anning electron microscopy.
