摘要

摘要高熵碳化物是一类新型无机化合物，具有广泛的应用前景。研究人员提出了一种新的概念，即通过无气热爆炸模式下的自蔓延高温合成（SHS），利用之前机械合成的结构化反应混合物合成高熵碳化物粉末。通过这种方法首次制备出了高熵碳化物 TaTiNbVWC5 和 TaNbVMoWC5，并测定了它们的晶体结构，并将其与烧结法合成的同类化合物进行了比较。

Self-Propagating High-Temperature Synthesis of High-Entropy Carbides in the Gasless Thermal Explosion Mode

High-entropy carbides are a new class of inorganic compounds promising for a wide range of applications. A new concept was proposed for the synthesis of powders of high-entropy carbides by self-propagating high-temperature synthesis (SHS) in the gasless thermal explosion mode from previously mechanically synthesized and structured reaction mixtures. For the first time, high-entropy carbides TaTiNbVWC₅ and TaNbVMoWC₅ were produced by this method, and their crystal structure was determined and compared with those of similar compounds synthesized by sintering.

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
