我们研究了燃烧合成（CS）与放电等离子烧结（SPS）制备的La掺杂SrTiO 3的优值，主要集中在烧结时间的影响。以氧化物、碳酸盐、金属和高氯酸钠为原料，采用CS法制备了Sr0. 92La0. 08TiO3样品，并在1573 K下进行了1、5、15和30 min的SPS处理，测量了其从室温到1173 K的热电性能。烧结5分钟的样品在1045 K时记录了最大的优值0.37。(C)2010 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
We investigated figures of merit of La-doped SrTiO3 prepared by combustion synthesis (CS) with post-spark plasma sintering (SPS), focusing mainly on the effect of sintering time. Sr0.92La0.08TiO3 samples prepared by CS from oxides, carbonates, metals, and sodium perchlorate were SPSed at 1573 K for 1, 5, 15, and 30 min to measure their thermoelectric properties from room temperature to 1173 K. The 5-min-sintered sample recorded the largest figure of merit of 0.37 at 1045 K. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
