论文摘要
本文中，我们证明了Bicuseo化合物可以通过反应性火花等离子体烧结（RSP）直接从原材料中形成，然后进行球铣削和第二个短火花等离子体等离子体烧结步骤。与通过常规固态反应获得的Bicuseo样品相比，RSPS散装的电运输特性受烧结技术的适度影响，而晶格导热率几乎不受影响，优点ZT的数字在773 K时获得了与正常情况下的Bicuseo相当的值。结果表明了一种用于制备氧yylenides的新方法。
Herein, we demonstrate that BiCuSeO compound can be formed in bulk directly from the raw materials through reactive spark plasma sintering (RSPS) followed by ball milling and a second short spark plasma sintering step. Compared to BiCuSeO samples obtained by a conventional solid-state reaction, the electrical transport properties of the RSPS bulk were moderately affected by the sintering technique, while the lattice thermal conductivity was almost unaffected, and the figure of merit zT attained a value at 773 K comparable to state-of-the-art BiCuSeO. The results indicate a new scalable method for the preparation of oxyselenides.
