Abstract

Sol-gel-derived nano-powders of lead magnesium niobate and lead titanate solid solutions (PMN-PT or PMNT) were prepared from lead acetate trihydrate (Pb(CH₃COO)₂·3H₂O), magnesium acetate trihydrate (Mg(CH₃- COO)₂·3H₂O), niobium ethoxide (Nb(OC₂H₅)₅) and titanium isopropoxide (Ti(OCH(CH₃)₂)₄). The key steps in the preparation process were discussed. The crystalline phases in the powders were investigated using X-ray diffraction (XRD) analysis and the size of grains was observed by field-emission scanning electron microscopy (SEM). These powders, with good dispersion characteristics and narrow grain size distribution (ranging from 50 nm to 200 nm), may be used to prepare PMNT thick films and ceramics.
