Using EDX analysis the evaporating of boron was confirmed and Cu 2+ most likely substituted for Zn 2+ sites in the phases Ba 4 ZnTi 11 O 27 and BaZn 2 Ti 4 O 10. BaTiO 3 phase appearing at the grain boundary as the derivative of BaCu(B 2 O 5) had a considerable negative effect on the microwave dielectric properties. The variation …The fraction of Sn and Zn (BaZn x Sn x Fe 12−2x O 19, x-0.2−0.3) was lower than in the target (BaZnSnFe 10 O 19, x=1). Nevertheless, no additional phases were observed with backscattered electrons. Therefore, we can conclude that the loss of Zn and Sn occurred during the deposition. 3.2.
