Description

Novel relaxor ferroelectric crystal 0.93Pb(Zn1/3Nb2/3)O3-0.07PbTiO3 (PZNT93/7) with dimensions about Oe40 x 70 mm3 was obtained by directional solidification technique. The growth defects of the crystal were investigated. Rocking curve analysis revealed the crystalline quality of PZNT93/7 crystal was not perfect and the FWHM value was measured to be about 0.7 . Some pits and oxide particles in micro-size were formed in the crystal due to the growth conditions. A series of growth steps parallel to (001) face were observed which were attributed to the growth behavior. Moreover, it was found the average chemical composition of the crystal was deviated slightly to the stoichiometric value of PZNT93/7. (copyright 2008 WILEY-VCH Verlag GmbH and Co.
