Abstract
Provided are novel high entropy nitrides (HENs) exhibiting excellent physical and chemical properties. Also provided are systems and methods to synthesize bulk HENs by reaction flash sintering. Commercial metal nitride powders can be consolidated into near fully dense single-phase bulk ceramic with a proprietary flash sintering apparatus. A constant DC electrical field of ˜80 V/cm and pressure of ˜15 MPa at room temperature can trigger reaction flash sintering without pre-heating, and the entire process can finish in ˜250 seconds to ˜400 seconds.
