221 Reaction synthesis of TiN and AlN in liquid nitrogen with wire explosion

Nitrides, especially titanium nitride (TiN) and aluminum nitride (AlN) are studied for their significant characteristics. But there are many problems of synthesis like microparticulation and synthesis time, cost reduction. A new method to synthesize TiN and A1N through electrical wire explosion of titanium wire and aluminum wire in liquid nitrogen is proposed. In this process, high-purity and nano-sized nitrides is recovered in a short time. In this investigation, the details of the method of wire explosion and some analytical results for recovered powders are described. Under a moderate condition, TiN and A1N powders were successfully recovered.
