Abstract

Substitution of neodymium for lead in the apatite structure in accordance to scheme 2Pb2+□ → 2No3+ + O2- has been investigated by X-ray powder diffraction, scanning electron microscopy, IR spectroscopy and the measurement of electrical conductivity. It was estimated 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.
