MANUFACTURING METHOD OF LEAD LANTHANUM TITANIUM OXIDE-BASED NANOPOWDER OF PEROVSKITE STRUCTURE

摘要

PURPOSE: A method for manufacturing a lead lanthanum titanium oxide (PbLaTiO3)-based nanopowder is provided to obtain the PbLaTiO3-based nanopowder of the perovskite structure having fine and uniform spherical shape.;CONSTITUTION: A method for manufacturing a PbLaTiO3-based nanopowder comprises the steps of weighing an oxide powder including a Pb component, an oxide powder including a La component and an oxide powder including a Ti component according to the desired composition of Pb_x La_(1-x) TiO3 (wherein x is a number greater than 0); and milling the oxide powders in a mechanical chemical mill provided with balls performing the linear motion and the reciprocating motion of 8 shape or lied 8 shape, to form the Pb_x La_(1-x) TiO3 nanoparticle having the perovskite structure.;COPYRIGHT KIPO 2010
