چکیده
|
Sodium europium silicate,naeusio with apatite structure has been obtained and studied using x-ray diffraction and sem. it has been shown that sodium sublimation does not take place upon synthesis by the sol-gel method. rietveld refinement has revealed that sodium atoms are ordered and occupy the 4f position. o(4) atoms not related to silicate ions are placed at the centers of eu(2) triangles. dc and ac electric conductivity and activation energy have been determined for the compound studied. © 2013 ekaterina v. borisova et al.
