摘要

This research work is aimed at lowering the sintering temperature of 0.9PMN-0.1PTceramics by adding oxide additives. The oxides used for this purpose were Bi203 andLi2CO_3with various amounts, following the formula of xBi_2O_3+yLi_2CO_3, where x+y =10 mol% and x = 1, 3, 5 and the mixed oxide additive powders were then added to thedried powder of 0.9PMN-0.1PT with 1 wt% concentration. An excess PbO content ofapproximately 3 wtadded to all compositions to compensate the lead loss. After that, themixed powders were pressed into pellets and subsequently sintered to form the ceramicsamples. The results showed that the sintering temperature of 0.9PMN-0.1PT ceramicscould be lowered down from 1250°C to 900-1000° C by the addition of small amountof the oxide additives, where the optimum composition was found in the sample withx : y = 1 : 9 at sintering temperature of 1000°C. Moreover, the densification, dielectricand ferroelectric properties of this sample remain acceptable in particular uses, promisingpositive future for reduction of lead loss from electrical and electronic industries.
