Abstract:

A new series of germanates CaRE2Ge3O10 (RE = Y, La-Yb) has been prepared using an EDTA-assisted route. Rietveld refinement of room temperature powder X-ray diffraction patterns shows that these compounds crystallize in the monoclinic system (S.G. P2(1)/c, Z = 4) and have two morphotropic transitions. The calcium and rare earth atoms are distributed among three nonequivalent sites and form layers along the {[}0 0 1] direction connected into the framework through {[}Ge3O10]. The morphotropic transitions are accompanied by changes in the site occupancy factors of metal cations and by variation in the first and second coordination spheres of Ca2+/RE3+.
