Growth and structural characterization of lanthanum doped lead titanate fiber
Lanthanum doped lead titanate Pb 1-x La x Ti 1-x/4 O 3 fibers (x =0, 5 and 15 at%) were grown by sol-gel technique and characterized for their phase formation behavior and crystal structure. The precursor sol was concentrated upon heating at 100 o C to make it spinnable and used for fiber drawing. For heat treatment, a two step-heating schedule was designed on the basis of DSC analysis of the as drawn fibers . X-ray diffraction analysis showed that the tetragonality of the Lead Titanate (PT)doi:10.1080/10584580008216673 fatcat:hltqwynkebdp7exw7lr6whhoia
