Containing lead titanate composite oxide dense polycrystalline sintered body and manufacturing method thereof having a perovskite type structure

摘要

[Abstract] The present invention while suppressing the grain growth, the perovskite structure PbTiO ₃ particles of sub-micron particle size is the main object of the present invention is to provide a method to be densely sintered. A method for producing a high-density lead titanate polycrystalline sintered body having a particle size of submicron to a PbTiO ₃ powder 0.15μm following monodisperse, characterized in that the spark plasma sintering.
