Abstract

High-entropy ceramics (HEC) are an interesting class of high-entropy materials, showing remarkable properties, allowing flexible ways to obtain a combination of properties in a single material which has application in diverse fields. Synthesis of stable high entropy oxides was achieved in 2015 and other classes were synthesized right after. A promising class of HECs that have gained attention recently is high-entropy nitrides (HEN). As with high-entropy alloys (HEA), the primary challenge is the synthesis of stable high entropy single phase materials. In this work, some recent HECs are discussed along with the synthesis procedures and novel applications. Furthermore, new synthesis routes are investigated for the formation of a high-entropy nitride constituting late transition metals.
