ABSTRACT:
This invention provides a hybrid Stockbarger zone-leveling melting method for seeded crystallization and the manufacture of homogenous large-sized crystals of lead magnesium niobate-lead titanate (PMN-PT) based solid solutions and related piezocrystals. The invention provides three temperature zones resulting in increased compositional homogeneity and speed of crystal growth, in a cost effective multi-crucible configuration.
