چکیده انگلیسی
Dense BaCe0.5Zr0.3Ln0.2O3−δ (Ln = Yb, Y, Gd, Sm, Nd and La) proton-conducting ceramic materials are successfully prepared by solid-state reactive sintering method. The XRD analysis shows that the surface of ceramics is characterized by a pronounced texturing, whereas the volume of the same samples (obtained by grinding of ceramics) reveals the typical patterns. The degree of surface texture for BaCe0.5Zr0.3Ln0.2O3−δ (Ln = Yb, Y, Gd, Sm and Nd) samples is ranged between 24% and 39%, whereas for the BaCe0.5Zr0.3La0.2O3−δ ceramic it reaches 99%. The possible reason of particular texture of ceramics is proposed.
