Structural phase transitions in the relaxor ferroelectric Pb{sub 2}Bi{sub 4}Ti{sub 5}O{sub 18}

The relaxor ferroelectric Pb{sub 2}Bi{sub 4}Ti{sub 5}O{sub 18} has been studied by Rietveld refinement of powder neutron diffraction data collected at temperatures of 100, 250 and 400 deg. C. Our refinements are compatible with the 'average' crystal structure of Pb{sub 2}Bi{sub 4}Ti{sub 5}...
