Abstract

The stability of the lead scandium niobate (PSN) and itssolid solution with lead titanate (PSNT), both with the perovskitestructure, was investigated in a platinum capsule under hydrothermalconditions. The perovskite solid solution of PSNT decomposes in waterat 640°C, which results in the transformation to thetetragonal structure after the treatment. In KOH solutions, the PSNTpowder was partially dissolved, it results in the precipitation ofPb2ScNbO6 powders with the perovskite structure, and thegrowth of both lead oxide (massicot) and K4Ti3O8needle crystals at the top of the capsule. In contrast, singlecrystals of both PSNT or PSN were grown in KF solutions at the top ofthe capsule by hydrothermal treatments at 600°C with atemperature gradient of 40°C. In both cases a deficiency ofthe scandium content achieves the stabilization of the pyrochlorestructure of the grown crystals.
