For widespread application, the preparation and subsequent consolidation steps of thermoelectric materials should be rapid. Therefore, the single-step preparation of a dense specimen from commercially available precursors is desired. But the undeniable fact, that dc-current had a significant influence on the reaction between the components in the SPS, due to increasing the kinetic of the solid-state reactions, as results, a reducing the synthesis time from days / weeks to minutes / hours. Using the dc electrical current in SPS process open us new opportunity to obtain the new materials, which are impossibly to prepare by other synthetic methods. Understanding the detail mechanism of this process will be the focus of our investigations.

对于广泛的应用，热电材料的制备和随后的合并步骤应迅速。因此，需要从市售前体中的密集标本的单步制备。但是，不可否认的事实是，由于增加了固态反应的动力学，因此DC电流对SPS组件之间的反应产生了重大影响，结果是结果，将合成时间从几天 /几周 /小时 /小时减少了。在SPS过程中使用DC电流为获得新材料打开了新的机会，这是通过其他合成方法准备的新材料。了解此过程的详细机制将是我们调查的重点。
