A team of researchers at the University of Birmingham have recently discovered a new form of refractory high-entropy nitride (NbMoTaWHfN) that has a higher melting point than any other known refractory material. This breakthrough has potential implications for the development of equipment that operates under extreme temperatures, such as aerospace and nuclear industry components. The new material was achieved by a technique known as spark plasma sintering, which involved applying a combination of pressure and electricity to a mixture of elements to create a dense and homogenous material. The team believe that this technique could be used to create other high-entropy nitrides with different physical properties.
