    摘要:

    采用燃燒法制備10ScSZ粉體,利用等離子放電燒結(jié)(SPS)制備10ScSZ細(xì)晶致密陶瓷塊體。根據(jù)SPS上下電極間距隨燒結(jié)溫度變化制作燒結(jié)曲線,在1200 ℃附近電極間距最小,判斷陶瓷致密化溫度在1200 ℃左右。為驗證該方法的可靠性,選取1050 ℃,1100 ℃,1150 ℃,1200 ℃,1250 ℃作為燒結(jié)溫度分別制備樣品。結(jié)果表明在1150 ℃燒結(jié)的10ScSZ樣品具有最高的致密度,達(dá)到99.4%,且具有平均晶粒尺寸為194 nm的細(xì)晶結(jié)構(gòu),與推測結(jié)果基本相符。該實驗結(jié)果證實了在SPS燒結(jié)中通過燒結(jié)曲線判斷合適的燒結(jié)溫度是一種高效可行的方法。

    Abstract:

    Fine-grained compact 10 mol% scandia stabilized zirconia (10ScSZ) bulks were sintered by SPS using powders synthesized by the combustion method as raw materials. The densification process of as-processed powders was investigated by measuring the real-time ram displacement of SPS during heating. It was estimated that the densification temperature of this material was around 1200 ℃ at which the ram displacement is minimum. In order to verify the effectiveness of the approach, 1050 ℃, 1100 ℃, 1150 ℃, 1200 ℃, 1250 ℃ were chosen as the sintered temperature to prepared bulk samples respectively. The results revealed that the 10ScSZ sample sintered at 1150 °C had the highest density, reaching 99.4%, and a fine grain structure with an average grain size of 194 nm, which was basically consistent with the speculated results. In this study, an efficient and reliable method was proposed and confirmed for judging the proper SPS sintering temperature through the densification development.
