Production of Nanosized Powders of Ferroelectrics with Narrow Particle Size Distributions

摘要

Functional materials containing ferroelectric crystals of metatitanates of divalent metals (barium,strontium,lead) are promising for manufacturing optical and piezo ceramics,ceramic memory elements,and artificial photon structures with energy gaps [1-6].To obtain such materials,it is necessary to have single-phase ferroelectrics with stoichiometric composition in the form of nano- and microcrystalline powders with given narrow particle size distributions.Methods for producing powders with a given particle size have not yet been developed.
