A new process of synthesizing metal and metal nitride powders by spark discbarge between two metal electrodes in liquid nitrogen has been studied. In this paper, the pbase and shape of the syntbesized powders by using titanium (Ti) , aluminum (Al) and tungsten (W) electrodes are reported. In the cases of the same metal electrode couple, titanium mitride (TiN) , Al and aluminium nitride (AIN) , W and beta-tungsten (β-W) were formed from Ti, Al and W electrodes, respectively. Sphericalparticles appeared in all the cases. In the cases of different metal electrode couple, the powder swere the mixture of particles forming from eachelectrodes, Since the particle compositions were nott uniform in BSE images and EDX spectr.
