Ultrafine TiC_0.29N_0.38 powders with a particle size of approximately 170 nm were synthesized by mechanochemical synthesis combined with moderate‐temperature annealing using Ti and ethylenediamine as raw materials. Ethylenediamine plays a versatile role in the fabrication of ultrafine TiC_xN_y powders. It can serve as not only carbon and nitrogen sources, but also a process control agent, that facilitates the generation of ultrafine particles. A dense TiC_0.3N_0.39 ceramic with a high hardness of 16.7 GPa was obtained by spark plasma sintering at a considerably reduced temperature of 1100°C. This simple, energy‐efficient method is a novel approach to synthesizing valuable TiC_xN_y.

机械化学辅助从金属和有机前驱体合成碳氮化钛

通过机械化学合成结合以Ti和乙二胺为原料的中温退火，合成了粒径约为170 nm的TiC _0.29 N _0.38超细粉末。乙二胺在超细TiC _x N _y粉末的制造中起着多方面的作用。它不仅可以用作碳源和氮源，而且还可以用作过程控制剂，以促进超细颗粒的产生。通过在大大降低的1100℃的温度下进行火花等离子体烧结，获得了具有_16.7GPa的高硬度的致密的TiC _0.3 N _0.39陶瓷。这种简单，节能的方法是一种合成有价值的TiC的新颖方法_X Ñ _ÿ。
