包括常规人造超硬轻元素氮化物（诸如立方氮化硼（cBN）、立方氮化硅（γ-Si 3 N4）和碳氮化物）的氮化物材料已广泛用于机械加工（例如，由于铁合金具有高硬度、高熔点、优异的化学稳定性和热稳定性等优异性能，因此可广泛应用于切削、磨削、镗孔、钻孔等领域。然而，在某种程度上，超硬氮化物仅仅弥补了金刚石的不利限制：在中等温度下的反应（与铁），氧化和石墨化;由于与金刚石相比，它们的硬度相对较低，因此仍然无法主导市场。因此，最近的努力朝着制备具有优异的机械性能和化学惰性的氮化物材料集中在合成三元轻元素氮化物化合物和收获的效果，通过微观结构的操纵加工硬化。这些新的轻元素氮化物是切割行业中取代金刚石的潜在候选者。另一方面，将过渡金属原子引入到二氮三键中可以形成新型的硬质过渡金属氮化物合金（TMNA），例如Mo-N、W-N、Pt-N、Ir-N、Os-N等，其是用于铁族金属的切割、涂覆和抛光的潜在候选物。然而，通过传统途径合成高结晶度和化学计量的TMNA是具有挑战性的，因为在环境条件下，过渡金属晶格中嵌入的氮在化学上是不利的。近年来，一种涉及在中等压力和温度下的离子交换反应的新方法被开发用于制备结晶良好的化学计量比TMNAs，其已迅速实现为电子学、催化剂和超导体中的新兴材料。
Nitride materials including conventional manmade superhard light-element nitrides, such as cubic boron nitride (cBN), cubic silicon nitride (γ-Si3N4), and carbonitrides, have been extensively used for machining (e.g., turning, cutting, grinding, boring, drilling) and coating of ferr ous alloys due to their remarkable performances of high rigidity, high melting-point, and prominent chemical and thermal stabilities. However, to some degree, superhard nitrides merely compensate for the adverse limitations of diamond: reaction (with iron), oxidation, and graphitization at moderate temperatures; they are still unable to dominate the market owing to their relatively low hardness when compared to diamond. Therefore, recent efforts toward the preparation of nitride materials with outstanding mechanical performance and chemical inertness have focused on synthesizing ternary light-element nitride compounds and harvesting the effect of work hardening through microstructure manipulations. These new light-element nitrides are potential candidates to displace diamond in the cutting business. On the other hand, incorporation of transition-metal atoms into the dinitrogen triple-bond can form novel hard transition-metal nitride alloys (TMNAs), such as Mo-N, W-N, Pt-N, Ir-N, Os-N, etc., which are potential candidates for the cutting, coating, and polishing of iron-group metals. However, synthesis of high-crystallinity and stoichiometric TMNAs via traditional routes is challenging, since the embedded nitrogen in the transition-metal lattice is thermodynamically unfavorable at ambient condition. A novel approach involving ion-exchange reactions under moderate pressure and temperature has been developed in recent years for preparation of well-crystallized stoichiometric TMNAs, which have quickly been realized as emergent materials in electronics, catalysts, and superconductors as well.
