摘要：
Centimeter-sized BaTiO3 and Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PMN-PT) single crystals were fabricated by the solid-state single crystal growth (SSCG) process. In the SSCG process a single crystal seed is diffusion bonded to a polycrystalline body and then heat-treated at a temperature where the single crystal seed can continue to grow into the polycrystalline body. BaTiO3 single crystals grown by the SSCG were used as seed crystals for the SSCG of PMN-PT as well as BaTiO3, because they were economical and chemically stable in PMN-PT ceramics with excess PbO. SrTiO3 single crystals could not be used as seed crystals for the SSCG of PMN-PT, because they were chemically unstable and recrystallized in PMN-PT ceramics with excess PbO. Compared to the conventional single crystal growth methods for BaTiO3 and. PMN-PT, the SSCG process was demonstrated to be much more cost-effective and. adequate for mass production of large single crystals of BaTiO3 and PMN-PT.
