Abstract

Single crystals 0.26BiScO 3-0.25Pb(Mg 1/3Nb 2/3) O 3-0.49PbTiO 3 [BSPMNT] have been grown for the first time by the solid-state crystal growth (SSCG) method. A 〈110〉 oriented Ba(Zr,Ti)O 3 crystal seed was embedded in a matrix of BSPMNT compact which was annealed at high temperatures to induce the single crystal growth. Various fluxes, including Bi 2O 3, LiBiO 2, PbO/LiBiO 2, and PbO/Bi 2O 3, were used and their effects on the microstructure of the annealed compacts and the single crystal growth behavior were investigated. In the annealed samples with PbO/Bi 2O 3 flux, a considerable single crystal growth occurred at 1050 °C (with thickness on the order of 500-1000 μm), without the formation of abnormally large grains in the matrix. The results were explained in terms of the effect of various fluxes, based on the grain growth theory.
