Synthesis, characterization and electrical properties of Pb(₈₋x)Na₂Ndx(VO₄)₆O(x/₂) solid solutions
Substitution of neodymium for lead in the apatite structure in accordance to scheme 2Pb²⁺ +□ o→ 2Nd³⁺ + O²⁻ has been investigated by X-ray powder diffraction, scanning electron microscopy, IR spectroscopy and the measurement of electrical conductivity. It was established that single phase solid solu...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Substitution of neodymium for lead in the apatite structure in accordance to scheme 2Pb²⁺ +□ o→ 2Nd³⁺ + O²⁻ has been investigated by X-ray powder diffraction, scanning electron microscopy, IR spectroscopy and the measurement of electrical conductivity. It was established that single phase solid solutions Pb(₈₋x)Na₂Ndx(VO₄)₆O(x/₂) are formed in the range of x = 0-0.25. The crystal structure features of some samples have been refined by the Rietveld method. It was shown that ions Nd³⁺ preferably occupy M(1) site. Influence of the composition x on the electrical conductivity and activation energy has been investigated.
