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.
